Tired of Telkom

I took out a contract with Telkom last year firstly it took them 2 weeks to deliver the phone there after they sent 5 phones in error. Ive been having problem with my handset for 6 months every time i go to a telkom store no one is able to help me i get told to go from here to there. I have had it with there pathetic service and i will make sure I let everyone know what a terrible company telkom is to deal with. The only thing they need to do is change the battery and they want to book the phone in for that its utter nonsense. As far as Im concerned telkom can shove their contract and they will see how they will get me to pay for it. Im not paying for a service Im not receiving.
