NO ANSWER FOR THE LAST WEEK

I am so glad that my contract is coming to an end cause to get no service from MTN call center is really bad. I logged a call last month for optimize billing that I am still waiting for. I have 2 reference numbers and numerous phone call that I made (*** / ***) I've asked for this last month. Nothing was done about this and after wards I could not get through so I've decided to leave this, until I got my bill to pay you. Only to find that I have been charged for this billing .... and I have not received this. Why must I pay for something that is not done from your side... I want my billing to be fixed and the extra charges to be taken off ...<br>
