Subscription inaccuracy and account overcharges

I app**** for a home wifi number at Telkom Fourways. Two contracts were created in my name for R199 and R299 respectively despite asking for a single connection. I have been invoiced for both, told I am using both lines and they have proof which they wont share. Cases consistently logged and closed with no feedback or reason why, weekly visits to the store for updates, Whatsapp support is useless as is trying to get through to their service desk, phone disconnected for a month despite paying for the service I ordered and again today told "we will escalate your issue". This truly is shocking way to treat a paying customer!
