SHODDY TREATMENT

I recently bought data for a friend of mine on the Standard Bank App. Let me state up front that I entered a wrong digit (instead of an 8 I entered a 7). The money was deducted from my account and only then did I realise the I had made a mistake with my friend's cellphone number. I checked the prepaid history on the app and was relieved to see that although the money had come off my account, some unknown person did not receive a surprise gift of data. I called the bank to email what had happened and asked them to reverse the transaction but was told that I would have to approach Telkom for a refund. I found this very strange after all I bought the data from the Standard Bank App. If I buy anything online from the local supermarket and find something wrong with it, the supermarket would either replace or refund. They would not send me to the supplier would they? This is what I felt Standard Bank was asking me to do. I did send Telkom a ease call me email twice and received a prompt reply that some would call me (even providing the telephone number I would receive the call from) Still waiting for the call. Sent emails to Standard Bank : Still waiting for a reply. Now I am not talking about refunding a great deal of money. It is more about receiving shoddy treatment and terrible service.
