Disgusting customer service on incorrect billing!!

I am terribly upset at the level of service i have received from MTN over the last month.<br> They are quick to debit my account, but when it comes to resolving issues,I as the customer have to follow up and make numerous calls to enquire.<br> <br> i have logged a complaint with regards to being incorrectly billed on my account for Itemised Billing on the 11th September 2015. It is over a month now and i have been given false promises that the credit will be passed but nothing has been actioned<br> <br> I have spoken to a lady Mapasaka as well as her superior who goes by the name of Katherine and was promised that it was to be resolved around the 2nd week of October and i would be contacted in that regard. Nobody has contacted me since!!<br> <br> I then called on Tuesday 13th October and spoke to someone by the name of David Mapokane who mentioned he will escalate and come back to me and that it will be resolved<br> <br> i am yet to hear from any of your consultants or supervisors<br> <br> THIS IS PATHETIC SERVICE!! As a loyal customer to MTN for many years i have NEVER experienced such shoddy customer service and i am considering porting my number over to another network based on the horrid experience!!<br> <br> SORT OUT YOUR MESS!
