Bad service

My account was blocked 2 weeks ago because a lady reported me that she paid R300 into my account and i didnt send her the hairpiece as i was selling in fb market place. I explained to her that i had issues with the courier company, she reported the issue to Standard bank and they blocked my account till now. I called the bank and spoke to the ***** department and they said i must ask the lady to call the bank so that they can unblock my account. I asked her and she refused and the only way i was gonna pay her was to make a payment using my bank account and it was blocked. I then looked for cash and i deposited it to her capitec account on the 4th of August. I then asked the lady to call the bank and tell then that i paid her, she refused. I sent proof of payment to Standard bank ***** department and sent me a message that they will contact me. Till now my account is still blocked and I have money in it. I paid the lady her R300 but still.
