Absolutely Useless

I have several contracts with vodacom, 2 of which are linked accounts - I phoned customer care to query the status of these. The person I spoke to, tells me the no is a prepaid no which is ridiculous as I have emails from vodacom contradicting it. Then I had cancelled a contract with vodacom online, the device and sim were collected and almost a month later, nothing had happened until I called again on 29 and 30 Oct 2015 and 1 Nov! And I'm calling again now and no one knows what is going on. I still haven't been credited for the debits on my account. I haven't received statements for almost a year despite my complaining on every call I make to Vodacom. I am so sick of being placed on hold while someone gets more confused and doesn' help me at all. Can you people sort out your nonsense and give me my money back!!!!!
