Worst Service Ever

Worst service ever. I am always advised when i call that a Shalili Naidoo will contact me to no avail, she or nobody has called back since Miraj who was fantastic to onboard me but from there it has gone downhill in terms of customer service. My line is not activated and i was charged R946 in December for a service i have not used. Surely there are systems in place to check if the service was really activated and my numerous phone calls are recorded. I have had no feedback from Vumatel or Home Connect and need urgent assistance or a refund.
