Cash App complaint: No help recouping funds

On January 17, 2019, I sent $50.00 to the wrong recipient with very similar name. After two days I learned that my payment had not been received. The intended recipient’s name is MAMICHULA; the funds were sent in error to $MAMICHULA. The difference is the $ sign before the latter’s name. I contacted cash app customer service and was told that I should have cancelled payment within 24 hours. I explained that I only learned of this error after 48 hours. I was then told that I would have to contact the recipient $MAMICHULA and request that she return the funds back to my account. I made at least 4 requests that she do so but to no avail. She have never responded to my request. I continued to ask cash app customer service to assist me in recovering my funds. After months of not looking into the matter on my behalf I was told that there was absolutely nothing that they could help me with. I was also told that I would have no recourse because I initiated the action and she is not at fault. This bothers me that they have all the account information for this person to pressure her into doing the right thing but insist on doing absolutely nothing to help me after I made an honest mistake. Will you help me please?
