Overbilling of my Top-Up ***

I was a client of Nashua and now my account has been taken over by MTN. I have a R500.00 Top-Up contract plus I pay R140.00 for 1GB of data monthly (R660.00 always deducted off my FNB account).<br> Since March 2015 MTN have increased my payment to R815.00 and when I queried this in May, I was told that an extra 1GB of data was being loaded onto my phone which I did not request.<br> I was assured that this fault would be rectified, however it was not and for the past 5 months the extra R155.00 per month is being deducted off my bank account so instead of paying R660.00 per month I am paying R815.00 per month.<br> Despite numerous phone calls to 808 and visits to the Pavilion Branch and Southway Mall Branch nothing has been done. <br> I called the customer care at the beginning of last week again, just to check if the situation had gone back to normal, and I was most emphatically assured, that on 1 August 2015 the amount to be deducted off my FNB account would be R660.00. WELL THIS WAS NOT THE CASE as R815.00 was AGAIN deducted.<br> I am now very displeased with MTN and would be pleased if you could kindly rectify this most unsatisfactory situation.Thank you<br> Eve Scheepers-Viljoen
