Billing query still not sorted

This is a follow up query on the query i logged on the 26 May 2015 and as i expected I did not get any call from Mtn they only rep**** the only posted the reply on Hellopeter , and Wenzile's response is such that everything is ok according to their records but my account is still not being topped as agreed but I pay my account every month , my question is if everything is ok as per their records my is it that noone from Mtn bothered to call me and how can he say there is no such thing as internet usage of R3856 in my account that was never explained to me ? If that is not the case why was my account debited for R1606.00 on the 25th July which I went to reverse at the branch ? I also went to Mtn Maponya to query that on the 4th August 2015 unfortunately I lost the 2 reference numbers that they gave me and they promised to call me after 7 working days which has never happened right now I'm sitting with an sms that says my account will be debited for R4022.51 on the 25th of August , who is fooling who here and why is Mtn giving me such a treatment . I am on my Top up 100 and my debit order must run for I think R536.00 monthly . I need someone to call me back on my cellphone .
