Telkom, need I say more

I've been trying to cancel the adsl service I've been paying for for the last 5 years to move to a different provider. I've never received good customer service from Telkom, but then again who has. I started a chat as I'm always forced to do, you know, because of the 50 minute wait time that costs 100 airtime when you call. I chatted with Sibonelo Ndimande who originally asked me to verify my details. I did so and was given the balance owing on the account. Since the balance is in access of R900 I wanted to know the break down of the account. Sibonelo Ndimande then said they he/she can't help me because I'm a 3rd party. I could not be more in awe. I insured, years ago, to put myself on this account as I pay for the service. I said that Sibonelo Ndimande just gave me info on the account and now doesn't want to. I mean it's not like I'm asking for miracles. I just wanted a break down of the bill. I've endured Telkom for years and years as a service provider now all I want is for us to lessen our spend. I need 3 things:

1) why is my bill so high (actually ill just have a look at the bill. 2) when will my adsl line be put into the holding pool. 3) how much will I be paying for just the line. 4) have you guys been throttling the line and what was the FUP limit because the internet

It's just information, you guys don't even have to do any work. I know there is no hope for better customer service but at least give me the information I need.
