Ugly treatment of clients

I had made a request at Vodacom Chats in Cosmo city for a service which shouldn't take a day under normal circumstances to be rendered. 3 weeks later, I'm still waiting for my service to be rendered. The worst part is that the consultants don't care about the progress, they promise to call me each time I speak to them and they never does. I have to initiate the calls all the times and still the query remains unresolved. I have to rate this as one of the worst client service experiences and wouldn't willingly recommend any of my friends and family to go for Vodacom.
