Trade-in issue

I sent my old phone for trade-in in March and it has been two months without getting a credit. I instead got a "credit cancelled" notice. It has also been a month since I talked to a customer representative who confirmed the receipt of my phone but they were still processing it.

I've seen many posts having the same issue, but nobody is reporting if they received any assistance or credit. Delayed/cancelled credit is the main issue here, but the lack of communication is another one. I have never received any email confirmation that they received my old phone which worries me. The only confirmation I got was a verbal one from the customer representative.
