********** UPGRADE - NO HELP

On 18th February 2015 we noticed our data contract had jumped from R299 to R749 and knowing we had a limit on the account, we had a limit on this data, we went in to query this account. My husband was informed that \he"had upgraded the account to a normal cellphone contract. This was actually a ********** upgrade and this was not authorised by my husband. We were told to get a police report and come back with all the docs. On 19th Feb we submitted all docs at the Vodacom 4U store at Cape Gate and we were told we would get an answer within 14 days. On Friday 13th March I called customer service only to discover no one knew of this claim. Again we went to Vodacom 4U and again they sent our docs off with the promise of a response in 24hrs. Today we are still waiting and no one can help us. We cant cancel the contract and we are forced to pay the R749 a month until THEY can sort this out"
