Billing me for an account not in use

I have been requesting telkom to move my line in 10 April 2015. I was advised this can take months as the area im staying in does not have telkom infrastructure. I was then sms'ed on the 28th July saying my account is with mweb which is not and that they cannot move my line. since then i have been struggling to get through to them to assist me. im getting bills to my new adress but no internet or line installed. how can i be billed for a service that im not using since April 2015? can someone please get back to me
