10 min before my call is answered

I called customer care to port from vodacom to cell c as i just started a contract with you (cell c) i am holding for 7 minutes and still holding i am having second thoughts about my contract and about porting my number because this shows me if i have an issue its going to take forever to resolve and as a network service provider the industry that you are in is fast paste so for me personally to hold on a telephone line for more than 10min.....is a big No guys.
