Gift Card Not Recieved

Signed up for the AT&T fiber 300 plan and was told I’d get a 200 VISA gift card. A month and a half went by and still nothing in the mail or my emails. I called the reward center and the lady had said she could give me a 200$ Walmart gift card instead so that’s better than nothing. Still haven’t received that either and was told I could track it in 3-5 days on the reward center and still comes up as I don’t have any rewards.
