TERRIBLE NIGHTMARE

I've been with Telkom for 2 years now, never have I experienced a problem with my bills up until now. My account has been suspended because I was in arrears but they then deducted the full outstanding amount which was due with arrears and all. My account was then unsuspended and everything was okay until I received a bill of more then double the amount I'm supposed to pay. TOTALLY RIDICULOUS. Amount that was deducted is now showing in arrears. Like yes I missed one payment because of unforseen circumstances but for 2 years I've never ever missed a payment. Nobody can assist me in your stores and tells me to call in. I just think it's so unfair, I don't know why I have to write a complaint but the ONE TIME I actually have a problem Telkom is unable to sort it out for me. I've always believed in Telkom, and always told friends and family to go there but now I'm being doubled billed, my line gets suspended at anytime and I've received another sms this morning to say it's going to be suspended. ALL I WANT IS MY BILL TO BE FIXED I've got the proof of my payment that went off my bank why can't they just link it to my account and remove this mess? I'm sure you guys have a collections department. But I've tried calling in 6 times today and when I finally get through the system is offline, I know that's beyond their control but really man. This makes me want to move all 3 contracts and settle the entire contract and go elsewhere.
