Unresolved Two-Month-Old Amazon Prime Phone Case Return Issue

I bought a phone case from Amazon Prime and have been trying to return it for two months. However, I have not received a refund and have not received a response from them. It's extremely frustrating that no one seems to be taking responsibility for the product I purchased. There is no point of contact and no customer service. I'm at a breaking point, and if I don't hear back soon, I'll have no choice but to escalate this to the proper authorities. It's frustrating to see such a lack of support and follow-through, especially when you rely on a service like Amazon Prime for convenience and dependability. I'm hoping for a quick resolution, but my patience is wearing thin.
