Telkom Mobile - where logic doesn't exist!

After about half a year of going back and forth between the various Telkom Mobile depts regarding constant dropped calls, calls not going out or not coming in, sms not being sent (even though you still get charged for them?!) or not being received, voicemails that gets lost in cyberspace etc etc etc, they finally "admitted" they they are unable (or rather to *********** for that matter!) to solve the problem - but then still want me to pay a penalty fee for "cancelling" my non-working-contract - a cancellation request due to their own poor/lack of service - after me having still paid as usual every month since first bringing the matter under their attention +-6 months ago?! I then requested to speak to one of their cancellation dept managers just now, after which I held the line for a relatively long time only for the agent - who first tried his best to keep me with Telkom by offering me free mins to roam on the other SA networks via Telkom (as that's the only way they can assure good service - go figure!) - then first asked me whether or not the manager got back/through to me - which he obviously didn't - and then when I said no - he straight after that told me "no but by manager told me that he's currently in a meeting" - i.e. if that was indeed the case - why on earth would you ask me in the first place "did my manager take your call" - a call to which this same agent had to put me through to - if you "already know that he couldn't?! I'm so sick and tired of all of Telkom Mobile's lies and uselessness - will STRONGLY recommend to not make use of their services!!
