Capturing my Contract wrongly ended up on ITC

I had a 3G TOP-UP account with Vodacom that was due for an upgrade, i then upgraded to a wi-fi ****le and 3gig top up account for R299 p/m as i cant afford an open contract. the man at the Vodacom Store in Northmead Square did not have a system properly in place and had to work from a laptop that was disconnecting the hole time, i then asked him for the 3gig top up account with the wi-fi ****le which they did not have available,(i had my fiance with me that day to confirm all this) he then asked me/us A TOP UP ACCOUNT? we said YES and he captured it on his laptop, i received the ****le a week later, the first installment was less than R299,the next installment R2080! I immediately phoned Voda and they confirmed it is an OPEN contract, I need to go back to the Store as they must re-fund me the amount as it was there mistake, i went back just to find out the man who helped me was not working there anymore and they will need to pull up my contract and confirm what i signed, I reversed the amount and paid R299 in Vod.. account, i told the hole story to Vod.. and waited for there reply. 5months later on 20-04-16 I found out I was placed on ITC for R6295.60 i am still waiting for Voda..
