Double payment taken

<br> This email was send to MTN. but i have not received any response from them. Could you please investigate this for me. <br> It is with utmost frustration that I am writing to you in connection with my account with MTN.<br> <br> On 06.05.2015 an amount of R595.98 was taken per debit order from my Absa account (ref ***) and paid over to MTN. but according to a consultant at your Richards bay branch same amount was paid back to my Absa account - nobody can tell me why - but no evidence of such a transaction appears on my bank account. When I queried this with 3 agents at R'bay office as well as according to their manager who apparently worked at Absa before, nobody could explain this. So what happened to that money. This is what I want to know and I desperately need your assistance to clarify this please.<br> <br> I have received 3 sms from MTN i.e. <br> 1. on 28/6 a friendly reminder that my bank account will be debited by outstanding R1235.36 (2xmonths)
