outdated cables cause faulty, dead line

For the past 2 months, Ive experienced a crackling line which is totally dead now, Ive been having issues with my line since I changed from pre-paid to line rental a year ago, which I needed for MWeb internet, I used to have a perfectly working telephone line for over 20 years Now my line is completely dead. I am billed every month for a non line/or bad line . Its getting worse. I logged my latest fault on 1 September, after spending 2 weeks trying to phone the call centre. Either no-one answers or someone passes my complaint from one to another. I regret I never took down names. I finally got my complaint logged by going into a store. My ***. I would appreciate a better service for the money I pay Telkom every month, and especially having a working line to use .Im not a happy customer. Technicians have warned me on the many call outs this past year, that my cables need replacing as soon as possible.. Unfortunately both telephone and internet get affected due to the cables, as they are linked via the telephone connection which runs from the outdated cables. I just want Telkom to give me a reliable line service and provide us with better customer service.
