Inexcusable reversal

I have been a Capitec Account holder for a very very long time.<br> I cant say i was ever dissatisfied with my bank until last night. <br> I sold a motorcycle to a gentleman who is also a Capitec Account holder. The gentleman came and viewed the motorcycle was happy and proceeded to pay. The gentleman took the paperwork as well as the motorcycle and two hours later my account was stopped by Capitec. The funds were available and i even drew from my account. I proceeded to call customer care and i was told that i should go to my nearest Capitec bank this morning as the gentleman reversed the transaction. Now i am sitting without my money, my motorcycle and my documentation for the motorcycle. I dont have the gentlemans details only his intial and surname, phone number, text messages between us leading up to the sale and then the proof of payment into my account as it was a cash deal. I was told by the customer care consultant that a forensic investigation has to be conducted and i need documentation to prove that a motorcycle was purchased. I have only text messages as i said and proof of payment. This is inexcusable and most unacceptable. After this I think I will be changing banks.
