Vodacom Fibre and customer care

Vodacom fibre and customer care are the worst departments to deal with. After installing the fibre it only worked 30 % of the time and I spent most of the time calling Service Requests for it to be repaired only to be billed a full amount every month. After 6 months of paying for a non existence service I requested to cancel the account only to receive an invoice of R14 000.00. There was no resolution given for this account and now find myself on the Vodacom phone with useless departments to find a1 person to assist. I have been on the line for close to 3 hours this morning and still on hold yet with a another different department including holding times of close 15 minutes. USELESS. BAD Service.
