Incompetence of telkom

I took out telkom fibre from telkom and was paying my account on a monthly base for 10mbps uncapped and not throttled for an amount of R800. My telkom fibre was updated from 10 mbps to 20 mbps uncapped and not throttled for a monthly amount of R1000 and I continue paying every month. I was again contacted to upgrade my speed to 40mbps telephonically for a monthly amount of R1200 in August 2019 which i agree to. uncapped and not throttled My headache started in October 2019 when my monthly billing was nearly R2000 per month.I was billed for 2 subscription one for the 40mbps and another one for 20 mbps capped adsl. I phone in regularly and lodge a complaint and a query. Every time a receives a ref no and after talking to the call center they inform me they can see the problem and will rectify it. Later in the week I will receive an sms that states that my problem was resolved only to discover the next month that it was not. again a lodge aquery to rectify my account to no avail. I keep on paying my monthly agreement amount of R1200. My monthly amount accumulated every month for a subscription that was not compatible with my original account and which was wrongfully added. I lodge every month a complaint to rectify it but to no avail. Sometimes my account billing was rectified and the outstanding amount was removed. The nightmare continues. I exhausted all my avenues to rectify my account. My account was also suspended several times and after lodge a complaint my account was reconnected. only to be suspended again. It continued nearly 18 months when I informed telkom that I'm cancelling my account but never did they remove the wrong subscription. I request the tape irw my upgrade but to no avail They acknowledge it and send me an e-mail. My original 40 mbps was cancelled but they still bill me for the 20 mbps which I could not use. I took out a new fibre from another company that is also part of telkom. I lodged a complaint with Icasa but never received an answer. I discovered that telkom handed me over for non payment. I forward all my mails and ref no's to the company who informed them they handed the case back to telkom. because it was not a true reflection from Telkom. I found out that my credit record is affected because Telkom stated that I did not pay my account and still owe them R720. Please advise me on the way forward to resolve my issue. I will forward all my emails with ref numbers irw my complaints. I feel that a big company can manipulate any situation to suit them. I also have a cellphone contract with telkom which i pay every month. Unhappy customer A Lombard
