Breach of contract because of idiot staff members

Telkom is charging me for device which I have already paid for a over a 24 month period

I took out a contract January 2016, and after i month I advised telkom i am not happy with the amount of data i received, and requested to be migrated to a higher package. This was not done by telkom and i had to go through the complaints to have my contract migrated. After struggling to get this done for almost a year the complaints department finally changed the data and advised i would not be charged migration fee and my contract term would not change because of the inconvenience. As usual Telkom did not keep their promised and the staff does not leave notes and they do not do their job because I was charged migration fee which was waved after i had to through the complaints again. I have now discovered my contract term was also changed another promise not kept. I am currently paying for a device for more than 24 months which is a breach of contract and ******* my device was paid up end of Jan 2018 yet I have a bill which states I am still being charged for it what the hell is wrong with your staff one know what they doing everyone is *********** and a bunch of idiots who makes empty promises Just get back to asap like I have been requesting feedback for 2 months I will take this to the Ombudsman if you guys take this money from my account again this month
