TELKOM IS TRASH!!

In July i app**** for a Telkom SmartBroaband 80GB Wireless deal because i had to work from home, everything was sorted in July for the month of August. long story short i was debited monthly as agreed on contract, things took a sudden turn in September 2020 when i got my statement saying that i am due to pay a premium of 2 packages, like double what i had signed up for. I have called Telkom numerous times trying to find out what was happening, why am i being double billed, for a product i never signed up for? its only last week that they sent me this silly response "Your query will be attended to. Your case number is ***5. Please do not reply this Email" its been over a month now without any results yet they still want to charge me for something that is under investigation. I DIDNT PAY YOU TELKOM LAST MONTH BECAUSE YOU TOOK MONEY FOR A PRODUCT I DIDNT SIGN UP FOR!! NOW YOU ARE SENDING ME STATEMENTS SAYING I OWE YOU? FOR AS FAR AS I AM CONCERNED I ONLY OWE YOU R569.00 DUE ON THE 25TH OF NOVEMBER, GET YOUR DEPARTMENTS IN ORDER!! YOU ARE MESSING WITH MY FINANCES!!!!!!!
