NO ASSISTANCE OR RESPONSE AFTER 11 EMAILS SHOCKING

I have sent 11 emails and a previous report on Hello Peter and I still cannot get a response from anyone in the billing department to give me the urgent information I require. I always received my email bill every month and then it suddenly stopped and I was then under the impression the telephone devices we purchased were paid up and the email transferred to our new address - Telkom registered me on ITC for non payment - how was I supposed to pay for an account that I no longer receive. I have tried to get an answer on this matter even though the amount has been paid up and cannot get anyone from Billing to give me a reply - I find this shocking service.
