Telkom is a ****

Telkom is a ****. I called to change my debit date from last day of the month to the 25th of every month since I am now getting paid on the 25th but ever since that in May they have been trying to deduct on my account and when it bounced back they add their fee so from May I've been paying R1071 for a R445 contract when I called them they put a blame on their debt collection agency when I called that agency they told me they are not handling my account so it's been 3 months that I'm being debited R1071 but Telkom does not how to solve this yesterday I called they gave me a reference number for this case but no one is attending to it instead they have shut my network I can't call or do anything while and I don't owe them anything instead they taking R626 more on my account for the past 3 months I will never recommend Telkom to anyone.
