Pathetic False Charges

Firstly your call center bolt experience is horrible, I never get to speak to an agent who is most likely to assist with my query. I have few issues with Vodacom that I have been a customer of for more than a decade and yet I'm treated like trash!!! I have a new contract with Vodacom (R180) 2 sims - Samsung A22 30 months contract where I was charged for the contract before my device got to me and I was promised a refund. Apparently, the refund was credited to my account and I don't even know what that means. 2ndly last month I was charged R447 and I have no idea what it was for, that's when I tried to get help but I couldn't get through. Where I stay we do not have a Vodacom closer. I disputed the amount with my bank which is FNB and they gave me my money back. Now I get a statement that I owe Vodacom R738 for this month-end, how did I get there I have no idea and again I will not pay for this. I'm at a point where they can come get their phone and both sim cards. I am willing to go to another service provider My contacts are ***. I expect this to be resolved
