Bad service

I had been locked so many case number with Telkom regarding my poor network service . Every time I have to phone in to Telkom regarding no feedback from technical team and accounts department up to now still waiting for Telkom to come back to me with an answer why my network service is so bad but yet they don't this the way Telkom treat they customers. I need refund and close my account immediately. The time and airtime I waisted to call in to find out for for feedback nothing happen until to day my network is off so what's the sence of having a contract if you don't enjoy it Telkom please advise why don't you deliver the service as promised when you selling your products to customers . I will never ever take out a cell phone contract .
