I did the promotion for myrewards and got upgraded from 50/25 to 50/50. The promotion was suppose to be a free upgrade, but now my plan is showing that it went from $59.99 to $69.99. The fine print said there would be no changes to my current contract. I thought free upgrade meant no added charges! I had $25 in promotions and discounts for a 2 year contract before and now that has been removed. How do I fix this??
