Reversal

Hello Peter I'm a Tymebank client since 2016 till now. On the 1st or 2nd of September I made a transaction of R430. I sent money to the wrong person. So on the Tymebank App we don't have an option to reverse transactions. Since well Tymebank is a digital bank, I called the consultants to notify them of the error I have made and to please reverse my money. They gave me a reference number GTQ 91061 and promised to get back to me before the 10th of September, of which it never happened. I called them on the 11th of September and they are telling me that they can't reverse my money. How so??? I've been their loyal client for almost 10 years and now they can't reverse my money? I know it's a small amount but they must do the right thing. Other banking apps it's easy to do a reversal immediately but with Tymebank I have to struggle????? I trusted them but I feel like they have failed me. I'm so disappointed I'm even thinking of going back to FNB. I get my salary via Tymebank. I'm thinking of leaving them since well they have failed me. People don't leave your banks for Tymebank, when there's an emergency they will never assist you !!!!!
