Telkom's putrid service

I've been a Telkom customer for just under 2years now. I have a phone contract with them, and almost every interaction I've had with them has been absolutely putrid! Recently my account was in arrears, so I called in to find out how much I owed them in total and shortly after, I made payment of the bulk amount that I owed them. A few days after that I call in to find out what's going on as my services had not come back on .. and the agent I spoke to told me that my account was cancelled. Bear in mind, I had never asked them to cancel my contract so I'm quite surprised to hear that my account is closed after settling my bill. The advisor assured me that she would raise a case to find out what was going on and that they would get back to me with feedback. I didn't trust that any body would get back to me, because having been with them for almost 2years nobody ever gets back to you from Telkom. Anyway, I left my contact details and hoped to get a call back to explain what was going on with my account. In disbelief, i called back later that day or the day after and again the agent told me the account was closed. A week or two later, still nobody has gotten back to me regarding my account.. I call back and advisor confirms account is still closed the case is raised and still open nobody has taken ownership to it it's basically just laying there and nobody is doing anything about it. In the meantime, Telkom is trying to debit my account for large sums of money each month. Yesterday I was at the bank, that's where I saw the attempts from Telkom .. so I called them a few minutes ago to find out what's going on. Advisor tells me my account is active and with collections.. at this point I'm confused. I request to speak to a manager so they can fix what's happening and the advisor put me on hold and never came back to me(this is common behavior from Telkom by the way.. you never get to speak to a manager and when you're on hold expect to hold forever. You're forced to drop the line and redial. Which is what i did). I called again the agent also confirms my account being active and with collections.. I find this very unfair because it is Telkom who cancelled my contract without my say so.. it is Telkom who didn't get back to me after raising a case and now they reconnect without alerting me of what is going on and all of a sudden I have a huge bill outstanding when I'm only meant to pay R499 a month.
