Vodacom You Have Lost A Customer

I will never in my life buy at the vodacom online store. I purchased a tab with them and I want to return it within day 1. None of the agents were able to help me, instead they bounce around the departments without any help. I'm now even blocked from calling because I've called multiple times, as if it's my fault. No one responds to my emails. Vodacom you have lost a customer due to your poor service and lack of training your agents.
