Cashapp Allowed Fraud and Kept my refund San Francisco California

On 3/12/20 I placed an order with The Childrens Place through Cashapp. My order was shipped on 3/14/20. I contacted The Childrens Place on 4/6/20 regarding my missing order. On 3/27/20 Cashapp voided my transaction and never returned my momey. I have made a complaint to the Better Business Bureau about both incidents and today 4/30/20 I received a response from The Childrens Place stating they issued me a refund to Cashapp and that I need to take it up with them.

On 4/17/20 I closed my account with Cashapp due to fraud charges on 4/13/20 of $32.16 that they refuse to acknowledge, they told me to take it up with the merchant. The merchant informed me that Cashapp needs to file a chargeback because my card was being used by someone else. Cashapp refuses to resolve my issues and missing money.
