Dissatisfaction with the credit facilities and overall policy.

I opened a Rage account at the Jeffreys Bay store and only received a credit limit of R300. On top of it I have to pay some kind of deposit on every purchase that I make. I've done my calculations and discovered that I still have to pay the full amount plus interest when my payment is due. I would like to know why the deposits are not being deducted. Another concern is the lack of variety in their clothing range. The clothes are full and basic, it definitely lacks imagination.
