Horrible account management

I recently opened a Edgar's account in April , I did this to get a credit rating as I never bothered with credit when I was slightly younger . After 3 months I kept noticing that I was being charged for things , so I walked into an Edgar's and started asking questions, as every time I paid it didn't seem like the amount lessened. I was then informed instead of a 6 month interest free account , I was on a 12 month interest bearing account ! I was not informed ! So I'm 3 months I paid an amount of nearly 500 rand ! On items that didn't even amount to a 1000 rand ! Leave alone that I was told that Edgar's offers free services so I said okay to the lady who helped me , to find out that they were not free! I closed down the account and I had a few items in my hand , when I tried to redeem my U card points the lady who was helping me said there's something wrong with this card we can't get it out! The most horrible experience with Edgar's ever ! I am well aware it wasn't the cashiers fault she was very sweet about it, but Edgar's account has just been the biggest disaster and I wouldn't advise any one to open an Edgar's account, I am disgusted with what has happened .
