Double deduction dumb customer service

I have had my account deducted twice for unknown reason phoning customer care is a waste cause spoken to 4 different people and each had something else to say the last person logged a ticket with the collection team said Wil take 48 hours to call still waiting.My account is not right and nobody seems to be able to help.I never make payments in store but they load my account with in store payments and then I must pay it so if Vodacom account or a manager can phone me I'd appreciate it alot.What very baffling to me is that when I spoke to first person said my account is in credit and must email refund department to get refund the refund department says I am not in credit then the other 3 all have different things to say

Thank you
