THIS IS FUSTRATING

I took a Telkom contract with Mondo, in 2017.. I lost my job and stop paying the account, called to have my services cancelled was told that could not be done, as the account needed to paid 1st, account went into an overdue and services was suspended. My account started accumulating and i had to put an end to it, i settled the account in full and requested cancellation of services and a paid up later. TELKOM refuses to give me what i need, and call centre agents keeps telling me that i need to WAIT! because there is a process, I dont need those services because ive never benefited fitted from, my ITC is a mess and all i want for it to ne updated, the services cancelled and my paid up letter, Telkom wants to charge me another months subscription for SEPTEMBER MONTH and im not using the sim card anymore, my enquiries at other credit providers has been put on hold because Telkom/ Mondo does not want to meer me half way, this is how they make money out of people. As a customer i have all the right to cancel something i do not want! Telling me about 30days waiting period is pathetic. I need this to be sorted out ASAP! This is frustrating because when you ask assistance from someone superior i get told there is no one to assist me or no one im that position to assist, surely there is, ive paid the money in full, cancel my services with immediate effect and give my paid up letter! Obadsman needs to hear about this..
