In December 2021 there was an $800 promotional offer. I turned in my iphone 7 for a iphone 11 and it was verified that I was eligible for the promotion, and yet, to date, I have not received any credit. I have visited a storefront and called 8 different times, and each time it is verified that I am eligible for the promotion and that I will see the credit on my next billing cycle. To date, I have seen nothing!!
