TERRIBLE SERVICE!!! Makro Credit Card

Been trying to close my Makro Credit card for 2 weeks, every time I phone in they have an excuse waiting. AND the BEST EVER!!!!! On a ZERO balance (have paid a settlement amount which they have given me - mind you this amount was MORE than the OUTSTANDING BALANCE) they STILL CHARGE YOU INTEREST!!!! How is this POSSIBLE????

Never open an account with them!!! have been phoning every 48 hours to get a followup - as they advice you it takes 48 hours (business hours)..... just to be told to followup again in 48 HOURS!!! NO SERVICE WHAT SO EVER!!!!!!
