Telkom charged me double for fibre

I am working from home and internet connectivity is imperative. I switched to Fibre two months ago with the cost of R799 per month, which I have paid. But today Telkom suspended my connection due to non-payment. When I phoned, I found out I was billed double for two fibre connections, which is obviously wrong. Logged a dispute but it takes 48 hours so the only way I can get connectivity is to pay the double amount charged and hope they will credit it later. I tried getting hold of the lady with whom I ordered the fibre, but she has vanished from the face of the planet. Really not happy. I don't have extra money to dish out like this, COVID has hit us all very hard.
