Cash App complaint: Scammed my bank account

Cash App allowed the scammers to debit my bank account $500.00 on Oct 20, 2020 at 12:??pm and will not help me retrieve it during this time of the year. They told my bank that I allowed the scammers the transaction when I didn’t even have that money in my bank. I emailed them to help me and they said that they could not but they seen where the scammers bought a $500.00 gift card from Walmart. If only they could if emailed me that info or my bank. So what called Cooperate Walmart and told them my story have them the date Oct 20, 2020 at 12:??pm and they found the last four numbers of my Cash App card and gave me the reference number and I delivered that info to my bank. The bank inturned tells me if I could get something in writing from Cash App about the purchase maybe I could get my $500. back but guess what Cash App in an email for the third time said that they could not help me so I’m complaining and has made a complaint to complain.biz
