Difficulty ending expired contract

I'm very disappointed at the level of poor service that we are getting from Telkom mobile. Our cellphone contract has expired a while back and for over two months no one is willing to assist us in terminating it. We've been advised to go to the store and when we get there, we get redirected back to call center.

It's been an ongoing battle till the manager escalated the call and to our amazement, nothing further has been done. When we went back to the store this past Friday we were told that there's a backlog. Have I mentioned that we've been getting calls almost daily to upgrade our contract? When we ask for a proof so we can take to our bank to stop debit orders we get directed to billing department over the phone and guess what, billings sent us back to the store where we got no help.

The worst part is we get passed around like ***** and the customer service from the store is the worst. No one is willing to take the responsibility and assist. :(
