Back in September of 2018 I switched to Sprint to take advantage of an Iphone XS Max promotion. Per the terms of the promotion and the contract I signed, I was only to pay the tax on the phone and receive a $41.67 credit monthly for 18 months. At the end of the 18 months I would then be able to purchase the phone for the remaining balance. EVERY month I have had to take time out of my day to call Sprint to get my $41.67 credit as each billing cycle has 'conveniently' omitted this discount and been in breach of contract!!! I'm continually told that it was a 'glitch' in the billing cycle. How is it they're unable to rectify this 'glitch'?? If Sprint isn't going to honor their promotions, why do they even bother to offer them?!?? Are they assuming that I won't check my bill to see their error? As soon as this phone is paid off I'm going back to AT&T. This is ridiculous!
