Unacceptable Service Provider

Absolutely appalled at the pathetic service provision from Vodacom Fibre, each month for the last quarter I am needing to call In and log a service request for internet down. Upgraded as advised to a 50MGP yet the issues do not stop, one month an additional router was ordered on my name. Last month debited double and half times my rate and still awaiting my refund, latest issue the Vodacom is blaming Vumutel for canceling the fibre line.. everyone is up to something on my account but me. When asking about an urgent SLA, none can be given!!! Absolutely pathetic for SA's largest network, we pay more than we would at other service providers yet get the worst service. I expect resolution with immediate effect, working from home and unable to do so with the constant problems!!!
