Disgusted with the non service

I have been trying to get help for my sister as she has no access to a phone or e mail ,on her account for weeks now and find it frustrating to deal with Telkom .She in unemployed and called the call centre in November 2017 and advised them to cancel. The line was suspended yet last months statement was R7500. I called the call centre and they advised that the account was not canceled. I struggled to get it canceled and eventually I got a e mail from the call centre to say that the account is canceled but is now owing R14500. how does it double in a few days . I am trying to get answers but no one is assisting . I went onto facebook and complained as well but no help. How does an unemployed person pay that amount . Why did cancelation increase the amount . She wants to return the phone and laptop and that was stated in Nov when she called the call centre . Someone in the call centre did not cancel this contract and now this huge bill has to be paid. I want this escalated and someone needs to assist and explain things . I have even called the call centre to get help in reducing the R7500 and was told send an e mail to Andy Maboshego. But he never bothers to respond either . Why am I not surprised as the e mail contact centre is the same . her account details are ********** 95 and her ID ********** 201086. Yet I have two pending upgrades and I get called almost every day . Now why would I take on an offer with a company that has no concern to help a person in need
