Why oh why does it have to be so hard dealing with Telkom

Having such a terrible time dealing with Telkom, we have been into the store and asked for simple things like billing details to be changed and spend limits to be set on our children's phones which weren't done. When we query why there are subscriptions we are told we have to phone for assistance. I just spent over 40 minutes trying to get to the bottom of this and going around in circles and have had the billing lady put the phone down on me. I am at my wits end - not sure that even posting here will get any response but hoping that perhaps i might - it is really unpleasant constantly having problems like this :(
