OVERCHARGED

I was called for my two yearly upgrade on my ****le and opted to take the wifi ****le for +-R210pm for 2GIG. She had to call me back as I had to check first if i could afford the package. So I agreed and confirmed that when the 2gig is up, I would have to purchase more data. First debit order was for the amount of R743.00. i nearly died and called immediately, only to be told that i had an open contract and that i can cap it if i want to??? ***. So I asked them to go back to listen to the recorded phonecall as this was incorrect. So I capped both my accounts just in case. I was called over a week later and told that I had an open account once again and there was no cap of any kind to be seen on the ****le. So I blew my top and asked again to escalate the query and cap it. Today, i get a call to ask if i want to change my contract to top up as IT IS STILL AN OPEN CONTRACT AND MY NEXT BILL IS ALREADY R710.00. ***FFFFF!!! I refuse to accept this. Why would I have had to ask the salesperson to call me back if i could afford R700pm. and I made sure I said that if i needed any more data that I would purchase it myself because I know data is expensive. I want my money back!!!!!!
