Cash App complaint: Scammed from Cash app for over 7,000.00

I reached out to Cash app Support chat because they weren’t taking no calls because of system problems. I reached out because there was 478.00 missing from my tax return so as I was chatting with them someone called and said they were with cash App and said they called me to resolve the issue of my money missing. They sent a link from Instantrefundingdept on cash app he told me to press the button and I did then all my money disappeared, and the caller was no longer on the telephone. I tried calling back and it was a fake number! I then reached back out to cash App support chat, and they asked for my info I was hesitant because I just got scammed on the app. I eventually gave them my info because they said without it, they can’t create a case. I have reached out to them again and again and they always say we are working on your case it can take up to 10 days to hear back from them. tonight on 342022 I heard back from them, and they have denied my case they said I gave someone access to my phone. NOT TRUE AT all!! I told them it’s an inside job or they are hacked!! How can someone call me from cash app while I’m texting you for help! This is a disgrace!!! I need help to get my money back!!!!
