All because I used your self service, now I suffer

Yesterday in the 29th of February at 11:53am I made a payment of R725 to Telkom using their self-service.

I got a confirmation email shortly after Reference Number 331EOE290224 that payment was successful.

In the same day at 21:13pm telkom debited my account for R724. 55

I'm too poor for your bs. Please send back my money
