poor service from Telkom

the service from Telkom is really pathetic, still to get a concrete response on my query. yesterday i got a call from the retention's department who promised to get back to me before the end of the day, up to now still waiting,. i tried calling the call center, all they are advising me is to wait for the retention's department to call. they cant even connect me through to that department for me to get the issue solve. in the mean time they are keeping my line ( 15G package) which I am no longer using so that they can continue to charge me. is it too difficult to cancel and contract and upgrade. <br> <br> i was considering upgrading but due to poor service it seems better to terminate the services completely<br> <br>
