Terrible service from Webafrica

I contacted the Webafrica team via Whatsapp and they advised that our fibre line had been cancelled. They provided me with a voucher number to make payment for the Wifi and advised that it needs to be reactivated. I was on the phone with them for the whole day where they would cut calls, disconnect chats and no feedback has been provided. They do not answer their phones and their chat is basically non existent. Can someone call me back to sort this out ASAP please.
