Horrible service!!!!!

Since day one I have experienced terrible service from Telkom Mobile. It took nearly three weeks to port my number since I signed my contact with them. When enquiring about it -the clearly inadequate sales consultant opened another contract in my name. I am now being billed for two contracts. When informing them about it and asking them to fix it before the money is debited off my account... 10 business days ago - their repsonseis that theycan see there is a mistake.on their side...but they cant correct it! "I have to wait for.someone from back.office to contact me.." Another 10 days!!! Shocking service! I want to cancelmy.contract with TELKOM MOBILE.
