Cash App complaint: Scammers allowed to changed their Cash App Name

I reached out to Cash yet when I called the one 800 number you cannot speak to a human being I emailed them with my dispute incomplete in for detail even pictures the merchant said that they would give me a full refund I request a refund the merchant denied my refund several times I took a snapshot of the merchant laughing at me saying yeah I rip you off sorry cash app is saying that they still cannot do anything about my issue they do not know who I am I will take this further and she had some type of insurance to insure that scammers are not going through their app and using it as a gateway to Fraud people they have no back up on your end if the person does not provide the good and services then a refund should be provided. They have to have some type of insurance on this money and I will be finding out more as I’ll be doing more investigation into Cash App and removing my friends from Cash App and not using the services again it has absolutely no security and safety they informed me that there’s nothing that they could do however I challenge them and I beg to differ
