Vodacom and WASP services wrong billing

I am a loyal customer of Vodacom for the last +- 15 years maybe less. Not one time have i missed a payment or a debit order. But the service i am getting from them is pathetic. I signed up for a red vip package with a 5 g for R1.299 per month. To my horror i found out this month they billed me R3000 amd since May the wrong amount as well it +- R3.800 that they owe me. This was debit from my account and only Vodacom has had access to the account. Now they said its Wasp services billed me for services they billed me which i never asked for. Now Vodacom refuses to pay the money back but i never gave WASP services my billing details and i feel its Vodacom responsibility to refund me. This has been going for 2 weeks and i have no answer and they keep on shifting the blame. All i want Vodacom is to refund me how they get the money back from WASP is not my problem. I am not willing to lose money just cause Vodacom does not want to help me....if that is the case and they do not want to help me then i will go over to Cell C where i can get a phone a contract of 999 and 10 g uncapped. I want my money back not a credit my money. Hope someone from Vodacom can help me.
