Cash App complaint: I was promised to have my money returned still Nothing

On August 5 I was sending my Sister some money to help her out during this pandemic. I send 240 dollars via cash app. At first the payment looked to have been sent and a few moments later I receive a notice stating that my transfer was cancelled and that I would receive my money by Friday even tho their app’s support tab says I should receive it back immediately unless it was a debit card which it was not. As I look at the cancelation of my payment I see a message that says I would get my money back by Friday August 7. It is now Saturday August 8th and still have not received my money that cash app cancelled. There is no way to contact someone and speak with a live agent. You can only email them and their app says I should get a reply in 48 hours. I sent a message on the 5th and still I have not received a response regarding the money they took and failed to return to me by their given date.
