I switched from Verizon to T-Mobile earlier this year, it was a whirlwind of phone promotions and phone trade-ins. I traded in my Pixel2 with a value of $200. I received $20 credit instantly, and was told to mail back phone after I get my TMobile Samsung S20. Store sales said 4-6 weeks I will get the rest ($180) by check. Still no check, on app cannot find trade-in status area as mentioned in other community responses.
