A double debit for your mess and I have to wait 7 working days to get a refund

Vodacom strikes again with a triple debit and refuses to refund me. How do you add 3 insurance covers on 1 account. And on top of that create another account to debit directly from my bank account! Yho you guys are nightmares. I called on the 27th because a huge debit went off my account. I was told that a credit will be app**** by Vodacom insurance to my Vodacom account. I also spoke to somebody from billing who said the amount can be deposited back to me once the credit shows. I just called your call center. 1. Credit for the double insurance hasn't been app****. 2. I am told to wait a further week for a mess I did not create. I was inconvenienced by you lot but I must wait! Why? Your processes are disgusting. Can someone competent please call me and send my money back within 48hrs!
