Telkom accounts penalties for no reason

I have been with Telkom for numerous years. And have always paid my bill on time.... I usually pay it cash well before the payment date and have done so for years., however I have noted on the contract that if debits are run, it's to be on the last day of each month... Recently I upgraded all 4 contract that I have with them. First issue came a few months ago when they handed me over to lawers for non payment. No warnings, no calls or emails beforehand, nothing, just immediately passed me to the lawyers..... However, my account was never in arrears, always in credit.... Then recently I paid the monthly bill for September, and it reflected On there statement aswell, however they proceeded to run a debit on the 30th September and they themselves reversed it ( I never reversed any debits) ... Now I'm stuck with a penalty fee of over R200 that I was forced to pay this month... ( a penalty that was caused by their error, not mine).... When I went to a consultant to have this corrected, they had to call through accounts, I ended up needing to explain everything to this person in accounts that plainly insisted that it was my error and they refuse to correct or refund anything....... I have all the paperwork, names and dates to prove that they were at fault. But not even the supervisor on duty deemed me good enough to speak to or assist in this..... This is purely daylight *******, and I am not impressed in the least by the accounts department. They should be thoroughly investigated as this does lean on breach of contract......
