Bad service or should I say pathetic customer care, or just dishonesty9

Hi

I am so frustrated with this service from Vodacom, I have 2 cellphone contracts with vodacom. My husband has purchased a once off 10GB data bundle on the one number, then the end of that month they charged him AGAIN for that 10GB bundle, I phoned the call centre and cancelled the so call subscription,and they said we will not get charged again, then when we received the bill, this data bundle was double charged on our account, let me say that again DOUBLE CHARGED!!!! I phoned the call centre again and the lady said we werent double charged but it shows double on our account, I was in the mood to argue with stupid people so I just left it and asked her AGAIN to cancel the 10GB data bundle, again we received a bill with the 10GB.. I phoned again, spoke to Lerato - she promised me it is cancelled and will not be charged again, and guess what, End of April we are charged AGAIN for this data bundle. Is vodacom *****ing from us or does your staff just not know what they are doing????? Please sort this out and I also want a refund because I have phoned multiple times to cancel this

Thanks
