BIS, Account and THEFT (Yes MTN I said it)

We where Nashua Mobile clients until a while ago when MTN had bought over our contracts. We then started looking closely at our accounts and found that although we are top up clients our account varies each month. MTN has admitted to this and had refunded. Since December 2013 we have been charged BIS which stands for BLACKBERRY INTERNET SERVICES we have 2 SONY devices & 1 SAMSUNG 'since June 2014. This means that Nashua Mobile and now MTN has been *****ing R120-R180 per month from our account. If you add it up for the the SONY devices 18 x R60 x 2 = R2160 and for the SAMSUNG 12 x R60 = R720. We lodged a complaint at their head office on 14th Avenue RFQ*** about 2 months ago and ever since then NOBODY from MTN has contacted us. On top of all the *****ing of the BIS money, for 2 months now one of the SONY devices MTN data and airtime just dissapears. AND PHONING MTN's 808 NR. IS NOT AN OPTION. When my partner had send a report to hellopeter also about a month ago someone from MTN had rep**** but that was it. NOTHING from MTN.<br> <br> MTN is it not enough that you charge high phone & data rates, you have to ***** money from peoples accounts also??
