I have complaints from Wayfair. They sent me a wrong mattress. I initiated a return request. Their third party vendors came in and picked up my mattress and gave me a receiving. 

But wayfair never returns or refunded me the money, the status still says refund will be issued once wayfair receives the items.

It’s been 5 months. I feel cheated. I raised a dispute with Chase. Wayfair replied that I haven’t sent back any item and if yes, I need to provide a tracking number.

I didn’t have any tracking number since when people pick up any item, they do not prove any tracking id, they just provided me a returns with my signature and their stamp that the item has been returned.

Wayfair has cheated me on this one.
