Telkom very poor service once again.

Very poor service from Telkom. I was overcharged and when I spoke to someone after trying to get hold of them for almost two month now to explain my bill they said they credited it to me and that’s were the balance came from, however I was told they don’t do credits they only debit the balance the following week nevertheless I’m still trying to get a proper invoice explaining this for they keep on charging me that same amount. I have also been given numerous login details this week and not one of the login username and passwords work, I have called and emailed and I just get asked to contact another department. I have also asked for the relevant documents to cancel Telkom for I can’t login but keep getting different responses from different department. I have been sitting without Internet since Saturday and the additional data I now have to buy is costing a fortune for Telkom still hasn’t resolved the issue.
