Telkom please cancel the contract (STOP BILLING AND REFUND ME) not my number!!!

Hello Peter, Last week I complained here about Telkom for not cancelling the contract as the phone they gave me was faulty. The phone is with Telkom since March 2019 but am still billed every month for the phone Telkom took back but never cancelled the contract. So this morning I woke up my number deactivated. OMG! I dont know how to behave. Firstly, I made it clear that they must cancel the contact not my number. I joined Telkom contact with my number and it's BUSINESS NUMBER. So today I can't work bcs my line is off my clients cant reach me. Can Telkom pls do the right thing pls. Ref. No.: ***9 to assist them what they need to do
