Telkom charging for holding on a huge *******

I have serious problem with being charged for holding on whilst dialing to telkom telephone numbers. When i am being placed on hold by someone (telkom landline) especially when dialing from a cellphone for 30 to 40 mniutes and it is costing me a lot airtime and then in the end somehow is cut off accidently ,which means now i am loosing unnecesarry money ...telkom must either put that hang time on the receiver which is in most cases a big company or organisation or stop billing me while i am holding on to be connected to a operator ...it is a totally unfair practice which only cause damages to the caller although he or she didnt achieve anything during the hold on time but loose money and telkom and cellphone operators is coining in from me holding on.That is unfair and i want ICASA to take a serious look into it...
