Worse experience ever - No communication

I got a call, offering me telkom data for R199, which i accepted .

Firstly i was charged for them to send me a statement via post, paid and kindly asked them then to rather send me an email. My agreement with Telkom is to debit my account month end of which is the 31st or 30th depending on the month of which the debit order falls on the 1st of the new month.

So December Telkom DECIDES TO DEDUCT the amount on the 29th with no communication , and because i was away on audit i only managed to pay it the following month of which I accumulated interest that was more than my debit order, because i did not want to be listed i paid the whole amount with no argument.

Now there are months that my data gets depleted before month end which i patiently wait for the following month to get data, now out of the blue, this month my account was uncapped. HOW THE HELL DO AM I UNCAPPED WHEN I HAVE AN AGREEMENT WITH TELKOM FOR ONLY 15GIGS. From R199 to R700.75 that was deducted.

I refuse to pay this R500 , the agreement i have with telkom is R199 and not extra R500 that i have no clue comes from where.

MAY I please HAVE THIS CONTRACT TERMINATED WITH IMMEDIATE EFFECT , BECAUSE THERE IS NO COMMUNICATION WHAT SO EVER..

Will never ever do business with Telkom going further.
