Cash App complaint: REFUND

I placed an order through the website WISH using my CASHAPP card for a total amount of $343.89 on 022223 and the items arrived on 031723. The things that I ordered were clothes and I returned the items back to the merchant, the entire order to be exact. I filed a dispute with CASHAPP to have the money put back on my card and they denied my request which is really weird to me because the merchant WISH does not have any phone support at all how can they deny my claim and the refund of my money without doing their due diligence. I have been using CASHAPP for a while now and I have had so many problems with them and they seemed to be run by a bunch of foreigners who are rude as ever. I will be getting my money back and I need to find a new source to fund my money moving forward because they are not working for me and have not been for a while now. Always too many issues and problems with them constantly to no avail. How are you going to deny a dispute when you have not even investigated it all the way through?
