Telkom Nightmare - Simply uninterested in retaining me as a customer!!

I have an LTE contract with Telkom which has come to term. I am trying to change this contract to a month-to-month cheaper contract as I wait for fibre. I have called Telkom 15 times in the last 5 days, spoken to countless people, who simply are not competent enough to assist, as they refer to the 10213 services, expecting me to try numerous options(which I have tried) and still no one can assist me. Telkom walk-in store at Westwood, Durban, tells me it can only be done on the phone - what the hell. Telkom you are bleeding and yet you do not make things easier for you to retain your customers. The option left is for me to cancel this service altogether! Please help!!!
