Event Billing Telkom

Hi There, for months Telkom has been charging me additional fees "event billing fees" I had two contacts (1.mobile wifi 199 and 2.home LTE 399) however you keep charging me additional. the same thing happened last year then you gave me a new simcard and it worked now a few months later you charging me additional fees again. I went into the branch at N1 city and they said that my contract was open contract on the LTE 399? So I canceled the contract in Feb 2022. Now I see you charging me additional 149 even after I canceled my contract, which means you "Telkom" just moved it over to my 199 contract which doesn't make sense. this is robbing customers we all know that cancelling and following up process with things is a nightmare as your staff are never clued up and can never resolve the query.Ive been a customer from 2015 till now... Telkom leaves a bitter taste in my mouth!
