Telkom customer service is useless

Hi, in 2014 i took a cellphone contract with Telkom. They were running a special at that time and said i can add the cellphone contract onto my Telkom landline for a reduced monthly payment. At that time the land line was on my fathers name. When the contract was expired 24 months later, there was nothing wrong with the cellphone and i felt that i didn't need to upgrade when it expired. The monthly bill was much less and i could carry on using the existing handset and i was only billed for calls and data usage. I was satisfied with this. i carried on using the handset and simcard for over a year after the contract expired and had no problems with the service. when the cellphone started to give problems. i felt that now it is time for an upgrade. i tried to renew the same contract and upgrade it. Telkom told me that the the cellphone contract was linked to my land line and i need to cancel the contract and apply for a new one. the contract was on my fathers name and he was out of town at the time. So i asked them what was needed to transfer everything onto my name. they gave me a document for my dad to fill in and sign. i took the document back with a copy of my dads ID. Telkom told me that it will be transferred onto my name. the next month the bill came on my name. i was happy with that part of the process. Now i still wanted to upgrade my cellphone contract. So i went to Telkom and asked them what was needed to upgrade my contract. they reminded me that i need to cancel the contract 1st and apply for a new one. i filled out the cancellation form in the shop at midlands liberty mall in Pietermaritzburg. the sales rep that helped me made a copy of my ID and told me that he will send it to the cancellations department and the process would take 21 working days. this was on the 29th of November 2017. The sales reps name was Oscar. i waited more than 21 days and got no response from Telkom. I went back to telkom on the 16th of January 2018. Oscar was not there that day. i Spoke to Simo Philani. He checked the system and said that the contract was not cancelled and he has no record of it. so he said all he can do is send the cancellation from again. so i filled it out again and he emailed it to the service cancellation email address and gave me a copy of the form and the automated reply from the service cancellation email. i waited for more than 21 days again and still no response from Telkom. i called the number on the cancellation form and spoke to a consultant. She said that the contract is still on my Fathers name and the cancellation form was sent to the wrong email address and i must email the form to her and she will sort it out. i have received no feed back from the consultant. i tried emailing her again. I even gave her an alternate number to contact me. i tried calling the call center but no one answered. the automated message says all the consultants are busy. i waited for over 30 min. the call got cut. i tried calling a few times but no one answers. I am fed up now. I don't know what to do. i need a new cellphone contract but want to keep my existing number.
