INCORRECT BILLING

I am really not Happy with how MTN conducts business, I have been charged R399.00 More on my contract again,for what? my contract is R369 a month this is not the 1st time im expencing this<br> Mtn your service is pathetic. i have lost count of how many times i have phoned the 808 number which is a absolute joke.You get cut off, put on hold and ****to. I am paying every month for a service that i am not receiving and i consider that it is very poor and unprofessional. IM BEING CHARGED AREAS WHILE I PAID MY ACCOUNT,I PAID R400.00 ON THE 3RD OF JULY TO THEIR ABSA ACCOUNT *** I STILL HAVE THE PROOF AND I RECEIVED A SMS AFTER I MADE MY PAYMENT THAT THEY RECEIVED THE PAYMENT THANK YOU , AFTER FEW MINUTES I RECEIVED ANOTHER SMS STATING THAT I HAVE TO PAY R84.00 I CHECKED MY STATEMENT I REALISED THAT I MADE A SHORTAGE OF R53.00 I WENT TO MTN STORE IN FOREST HILL MALL CENTURION ON THE 06 JULY TO PAY R54.00 NOW ALL OF A SUDDEN MY JULY STATEMENT COMES UP WITH AREAS ON IT AND WITH THE BALANCE OF R768.00. <br> what I see is MTN does not want to take responsibility of what they have done,The consultant did not communicate with me he just hang up on me.Please assist me in rectifying this problem
