No follow up from MTN

I published a complaint about unauthorised MTN debit orders on 25 September and received a prompt reply from Complaints Analyst Alice van der Merwe that she had tried twice to reach me but had got voice mail both times. I then rep**** with an alternative number for her to try on 27 September and again - twice - on 1 October, together with more information about the problem. I have not heard another word. Would someone from MTN please go back to the original complaint and contact me on the alternative number given.
