Cash App complaint: Scammed by Cash app

Mother in law got scammed while creating a business account on cash app. She received an email stating that she had to tell the person who had sent her a large amount of money to send her an additional $250 in order for her to change her account to a business account. After she emailed Cash App about that, a representative emailed her to purchase an ebay gift card of $100 in order for the account to get activated. Once she purchased it, she received an additional email telling her that the Ebay card was invalid (which was not true bc the purchase at Dollar General had gone through) and she had to purchase an Amazon card of $100 in order for her to activate her business account (which she did not go purchase).
We had spoken to two people who claimed they worked for Cash App over the phone. The first person had gotten upset with my mother in law because she did not want to give them personal information CashApp states in their Terms of Service they do not ask for. The second person stated that Cash App was receiving scammers on their end since quarantine had started. He apparently was able to do a screen share of my mother in laws phone and when he attempted to send a transaction of $1.00 to her personal bank account since it did not work, he told us that he was going to send it again but then ended the call after telling her that.
My mother in law at this point is very upset to the point where she does not know what to do. She needs Cash App to resolve this situation as soon as possible.
