Pathetic excuse for a Service Provider

I have never in my life been more frustrated with a service provider the way I am with vodacom. Vodacom has decided to list me on the credit bureau for R398! which they did not bother to tell me about. Firstly i closed my account on 1 June 2020 and was told the account will be closed. No one told me that i will still be billed for June, i was told that all money that should be paid in will be included in the settlement amount. I called to query this and was told that my account was in credit of R800, so tell me how do i now owe R398? I logged a complaint with ref: *** and no one bothered to call me in a week ?? then i get an sms stating that the query is closed, but i was never contacted to discuss the terms. I called in again today only to find out now that they have handed me over to their "lawyers" for outstanding fees. How the hell when I was never made aware, nobody contacted me, i was not even given a letter !!!!!!!. Under the Consumer Protection Act this is really unfair and I demand for my name to be cleared. This really is the ****tiest network ever. Even their call centre does not work !!!!!
