Pathetic upgrade now inormase bill

I have had the final straw with Vodacom and will be moving all my accounts to cell C.<br> <br> I tried to upgrade online my 3GB TopUp data account to a 10GB TopUp on 10 Feb 2015, was told there are no stock and my device will be on backorder. <br> <br> - 2015.02.28 My account was still a 3GB TopUp<br> - 2015.03.23 Tried to cancel the upgrade<br> - 2015.03.25 Promised to be phoned by Vodacom on this matter and If I am not happy with the product the upgrade will be cancelled.<br> - 2015.03.27 Submitted a second request to be phoned <br> - 2015.03.31 My account was still a 3GB TopUp<br> - 2015.04.30 My account was still a 3GB TopUp<br> - 2015.05.31 My account is now suddenly a 10GB contract with a bill of R13933.62<br> <br> When I tried to phone and sort this issue out and was referred to the data department by 081946 with no answer. I phoned customer care just to find out that Vodacom is offline and unable to help me. <br> <br> How is It possible that I can get a R13933.62 bill when every single contract I have is a TopUp account? <br> <br> When the device was delivered, I had to sign for it without being allowed to read what I signed nor provided a copy of the documentation. According to my knowledge I have a 10GB TOPUP ACCOUNT
