Pay a bill

Hello. Many of you on here know me. Today I’m asking for immediate help to pay a bill. I’ve been out of work for two months due to a painful knee replacement surgery. I had a painter come today, he did an excellent job, at the end I sent him $300 on Cashapp. I pointed out the name and he confirmed. Unfortunately we both made a mistake. That wasn’t his Cashapp. The person who received the money immediately blocked me, because Melvin realize about 20 minutes later he didn’t have money. I tried to send the wrong recipient $1 and requested a refund, but he blocked all trans. Cashapp support is a joke and I don’t have anything left to pay him another $300. Please find it in your heart to help me. I pay all my bills and can’t go back to work until august
