telkom a waste of time

For the past 2 days I have been trying to get through telkom adsl dept but got no joy. Every single staff at call center that I spoke to are damn *********** and cannot transfer me to correct dept. Some try but without fail cut the call. It's so damn frustrating. I simply want my data to be deactivated immediately instead of on the 28th when it's scheduled to go off. I have paid until the 28th so no loss to them. Is this too much to ask for? Telkom s Internet stinks and wouldn't advise anyone to take Internet data from them. I seem to be continiously having problems with telkom. Frustrated N Moosa ***
