Really bad service

I rented out my apartment and previous tenant took out a Fibre contract. With Three Months to go i decided to take over to pay the last 3 Months of the contract and then take over the account. Every Month i make payment and then every Month i find my services cut off. This even though every Month i send through the proof of payment to a sales agent. when i get home at 17h00 there is no agents in there call centre available. This means no service until the following day. stay away from this atrocious service. no one knows whats going on there. absolutely useless. there is no way i am taking over this line from Webafrica. Definitely looking for a new service provider with an active support line.
