Cash App Cash appl stole $1500 from me Internet

I attempted to use cash all to transfer funds to an individual, I had used it in the past to send small amounts like $5.00 and it worked, this time I was sending $600 and the funds wouldn't transfer so I called the cash app support line spoke with a Lisa Paul who told me she could assist me if I purchased Google play cards and give her the numbers she could transfer the funds, I purchased $600 in Google play cards called her with the info she called me back and said I needed to have $1500 in the account to transfer $600, I then purchased $900 more in Google play cards called her with the info she then informed me $600 would be transferred and she would transfer the $900 back to me the individual never received the $600 and I never received the $900, I called again and was told it needed to be an even $2000 I then asked that the total $1500 be sent back to me and was told if I didn't send the additional $500 my case would be closed and I would not receive my $1500 back.
