Seriously Poor Customer Service

I called Vodacom customer care last week and explained that I took out a Vodacom contract at Game Lenasia, I asked the sales person if I could use the R350 airtime provided and purchase data, the answer I got was no and I have proof as my girlfriend accompanied me. So instead of converting my prepaid number to the contract my only option was to get a new number. I than discovered that I could purchase data with the airtime provided which really upset me, as now from being misinformed by the Vodacom sales person at Game I have to have 2 sim cards. Customer care logged my call providing me with a ref number S3-88V7H-HMDM indicating that they would convert my pre-paid number to contract with the R350 airtime which is what I would have wanted. But today I received a sms indicating that I should go take out another contract to have my prepaid number converted. They can check there call log records because they indicated they would have my issue resolved and now I receive this sms. This is really poor customer service.
