DOESN'T KNOW HOW TO CANCEL A LINE

Pathetic service to say the least... Used to have a Telkom fixed line at our old house that we used for internet service (through another ISP). Phoned Telkom on 14/03/2018 to request a line move, as we were moving, I was told by the representative that the turnaround time would be 2-5 working days for a representative to contact me to request our new address, etc. By 26/03/2018 I had not received any phone call or email from them, so I phoned again. I told the representative I spoke to that I would just like to cancel the line instead, and that I would no longer want to make use of the service. She said that she will be issuing a cancellation request and proceeded to ask me a couple of security questions. After the conversation, she said that the line would no longer be in service from 00:00 that same night, and that I will receive the final pro-rated bill in the end of March 2018. I received a bill end of March, but with no pro-rated amount added onto the normal subscription rate as settlement of my account. I proceed to phone them and spoke to a representative that told me no cancellation was lodged, as I had not cancelled online or via e-mail, I then was told to send the cancellation request form to ********** I continued to send through the completed form on 16/04/2018. I since forgot about this and on I remembered and phoned them again to follow up on 14/06/2018. I spoke to a lady that said there was no cancellation request logged on their side, that is why I am still being billed for the service. I then forwarded the initial cancellation request e-mail to her email address: ********** as she said she will make sure it gets cancelled. Today on 09/07/2018, I received another bill for the service at our OLD house, clearly depicting subscription amounts for May, June and July!! How is this even possible for a company to have not one, but an unlimited amount of *********** people working for them??!! I am utterly appalled by the lack of service I have received from Telkom, and will be cancelling by cellphone account as soon as the contract expires. I will definitely no longer be supporting a company that can't cancel a contract after everything is s****-fed to their employees. Just cancel my line so that I can move on and pay you what I owe you and not a cent more!!!!!!!
