At my wits end!

I'm at my wits end. I NEVER do reviews, but I'm sorry, this really deserves to be said. My account has been in arrears and that's all fair and well, I called in, in April to do some arrangement for my account being in arreas. I was given a set amount to pay every month to then catch up to my arrears and I was comfy with that. April I paid my agreed amount, May i paid double and then in June my account got cancelled and they slapped a R10000 fee on my account and cancelled my account. I've called in numerous times and literally just got transferred without my consent, the one agent was more lost than the next agent. The store wasn't any help either, although they even mentioned I shouldn't be paying that amount . R10000 is a lot of money, I would do something about it if it were my fault but this is all Telkom and I did my part. Ever since this has happened, I've sent 5 people away from Telkom so far and will continue to do so until this is sorted out by you guys. This is wrong of a business to treat their customers like this! I really hope something is done about this soon!
