Grandfathered Simple Choice

I left AT&T in 2013 because TMobile was offering educators a discount. I signed up for the Simple Choice plan for $25 per line so I had a total of 4 lines for $100+10% discount. My total bill was $100.77 a month with unlimited text, voice, and data. To qualify, I had to successfully verify my eligibility through their verification dept. every year. For 7 years I did this until just recently they denied my eligibilty because they claimed the discount was an error. Is that deceitful of TMobile or what? I wish companies would be held accountable for their false claims. I understand if a company needs to make changes but they should take good care of the customers who helped get them off the ground first. I also read an article about a blog from ex TMobile CEO John Legere, saying we would be able to keep our discount but I guess not! I guess that's the reason why he stepped down….because TMobile is corrupt!
