Absolutely No SERVICE

I had a wifi contract that expired in June 2018. I have been using and paying for what I use every month there after till now. I have been trying to apply for an Uncapped ADSL line or an uncapped WIFI package. Every time I try im told that they can't assist because I have an outstanding amount of R3000 on a previous landline account. I never before had any sort of telkom line or service. When I phone again, I am told that they can not pick up any previous or outstanding amounts against my name. I try to upgrade or apply for the line again, same story all over. I am tired of getting redirected all the time with no avail. Telkom's service sucks, Oh but wait, there are absolutely no service. I can not see how Telkom can still survive with this poor service they are delivering.
