"Uber" product, but abysmal service

As the topic say, this about "Uber" the brand. I have no complaints about the product/App, its top notch or even against the Uber Drivers. I've had gentlemen conversation and enjoyed the service. Its their Customer Service. To simply say, its "Abysmal" or maybe "Pathetic"

Story starts 6 months ago.I've been an Uber user, since they launched in India, probably from 2013 and have loved the service. I never had a need to go to their customer support team. Not even once, when I was in India. I had no need, because they were charging me right and the App had no issue. I would always give 5* rating and the Drivers were always nice and courteous. So back to story. I moved from Chennai to SFO and the day I landed here, but Uber trouble started. I activated by "HDFC International" credit card (Since no PayTm or Debit Card works here) and tried to hail an Uber ride. Credit Card failed. (Fail #1) I am sure, you were the 1st to blame the HDFC Credit card right. Nope, card worked perfectly. I was able to charge the card on a few Duty Free and some local merchandise with the same India card. So Uber says, I cannot use India Credit card, even though its international. I took a Pvt taxi and moved away with it. Since the brand was nice to me, I thought maybe some issue with their payment system with Indian banks, since they had some trouble lately

I reached out to their support for the 1st time and they said, some problem with the system (Fail #2) and then I was able to hail uber. I was happier :)
No, it was beginning of more troubles to come. 

One of the most sensible thing or lets say, "Common Sensey" thing a person would do, when they move to a new country is updating their mobile phone.And when I went online, immediately I updated my mobile number and Uber showed no issue, when I update the Country and Mobile. I tried to hail an Uber and most of the time, I had no issue getting the driver or so. It was when I first landed in Vegas, that I knew Uber had some issues coming inside Airport gates. So I waited waited waited for an Uber to arrive but no one called or when I tried calling the driver, I constantly got an error. Then Driver cancelled and I raised with Uber support, who said, I was unreachable. (Fail #3) No one from Support bothered to identify what happened here ? If I was in Uber Technical Support ,I would have done a Root cause Analysis, to find out, why a person who was hailing Uber for 3 yrs, had some trouble off-lately. If I was a "Support Tech" with some "Common Sense" would have done it proudly, even if it took me extra 30 mins. But no, uber seems to hire, "People who reply to Tickets" or for the lack of word "Treat customers as Tickets". Now, being from Support, I did my own RCA and found the issue to be with Uber's logic in handling phone numbers, when folks change their number. When you update the Phone#, Country & Location, they update the Number but not the Country Code. Simply pathetic. (Fail #4) Then, I sent out a couple of emails to their Support team. Can you believe a Company/Billion Dollar Company like Uber has not Support Portal to track their customer's Ticket, or maybe I am not a valuable customer to get their Ticket tracked (Fail #5). I think the year is 2016 and Customer Support tools like "Freshdesk" have been invented and helping businesses ;-) So I could never give my feedback to their Support team and their Support team has no clue on what my ticket is about and even when I tweeted, their Support asks me to DM my Email Address. Why ?? Can't you link my Profile with your Twitter & Email Address into a common profile. (UberFail #6)

Every time I would explain that I need to update my mobile number, someone will come back from their team saying, I can hail an Uber now. Really!!!! Is that what I reached out to Support ? 

I was happy they have an Active Social Support but what is the use of a Support team which treats a Tweet or a Customer as a Ticket and focuses more on CLOSING the Ticket, rather than RESOLVING the issue for the customer.

And to my amazement, even after writing my emails in English - Correction - Clear English - All I want to do is, Update my Mobile Number and Location to USA Number, they still think I am unable to get an Uber drive. OMG. Big Time UberFail#
