Cape Union Mart doesn't comply Consumers Act

I opened an account earlier in this year only due to wanting to increase my credit worthiness , I purchased on this account twice of which I made immediate payments in the store on the same day. Having left the store for that month Cape Union Mart actually owed me a balance of R15-00 , however after the first month I did not enter the store again or make any purchases at the store. After working out of the store and owing nothing I did not receive any statements or information on this account as everything was paid to date. After 3 months I received a message stating I owe so much and to my surprise , I was shocked and questioned myself of when I purchased and did not pay, only to realize they duplicated some payments and made errors in the first month and started charging me monthly fees , without informing of their errors or sending me statements. I will never deal with their credit facility again as customers are entitled to statements and information when stores make errors. Had I knew the same month errors were made I would pay anything outstanding immediately and no monthly accrued charges would have being accrued for store errors. Highly dissapointed in the services.
