No help but sending bills

I have been calling and sending emails since 6 March with regards to downgrading my package. I have suspended the line due to the fact that I don't reside at my old address anymore. The account cannot be cancelled as I have a Telkom mix. But I can't move the line at present. I received a bill for R1500 of a service I cannot use. I have asked numerous times to be called on Facebook as well. There are services that can be cancelled on my account and I want to downgrade to lowest line speed etc till I can move my line. Pls send a new bill with price for Telkom mix and laptops and lowest line speed with other services cancelled which I can't use now. I've been a paying customer for over 5 years and the one time I need help now one is willing to Co tact me. Unacceptable service.
