Was I wrong?

This is my story:

I moved to Canada for a better future 24 years ago. Since then, I have been working in the manufacturing sector. I started my career in Canada as a machine operator and recently, I lost my job as Operations Manager. I was in the market for a long term position in an established company. I worked hard & enjoyed every day of it, I progressed & succeeded in my career.

To make the long story short, after applying to numerous jobs, without getting any positive answer, I spread my search all over Ontario & Canada. I applied for a position in the Windsor area, which was 400km away from my home, as a Production Manager. My family agreed to move with me after my probationary period. Fortunately, I received a reply from the company and the events following that will shed light on my story.

I applied and received a call from the HR generalist from the company and had a short interview. After a little while, I received another call from the HR manager, having a detailed interview. Later, the company scheduled an interview with the COO and owner of the company together over the phone, but they both didn't call me at the time scheduled. After many emails and calls, I got the opportunity to talk to both gentlemen. The interview lasted around 45 minutes. We discussed my experience, their expectations, the company's profile and my salary expectation. I was quite happy that things were going the way I wanted.

Then, I was invited to visit the company in Windsor, so I could meet the management and see the plant. The meeting was successful and the job was offered by the COO verbally, with a promise that the official offer will be sent by email within a day or two. My salary expectations were discussed again along with other matters and were agreed upon by both parties. After 2 days, instead of the offer, as promised, I received a call from HR that they wanted to check my references before they gave the offer. I was pretty sure that I would get this job because of the positive response, so I provided them with 3 work-related references.

I waited eagerly, but again instead of offer I received a call from HR that both bosses would like to have a little conversation with me. So we set up a time to discuss and clear up any additional questions and concerns then told me they would send me the offer by that evening.

Again I waited 2 days before they finally sent me the offer. There was an issue: my salary, days of vacation and starting date were different from the numbers we both agreed upon. There was a line in the end, that the offer is for my review and if I want to discuss anything, please contact HR. I called HR and ask them to please correct my salary and vacation days. Also, I wouldn't have been able to move to Windsor within 2 days so I requested another week so I could arrange for my accommodation.

After a couple of follow-up emails, I received this answer from them:

"I apologize that we have not got back to you sooner. Unfortunately, we are unable to bring the base compensation to the rate you were looking to achieve. After discussing with the group we do not feel it would be a great starting point if the potential candidate feels they are not compensated appropriately for the role and have decided to rescind our offer. We appreciate the time you took to meet with us and the phone calls we have had and we wish you all the success in your job search."  

I am so disappointed. There was no counter-offer or formal discussion before they decided to withdraw the offer. Throughout my entire career in Canada, I negotiated my salary and benefits every time I switched jobs and no company ever had an issue with it. My question to all of you is: was I wrong to point out the issue I had with my wage and vacations when it was decided and agreed on several times? Or does the company believe that the employees are not allowed to discuss their rights and was the company not trustworthy enough to keep up with their words?
