Unfair

To whom this may concern...I have received a debit order instalment for January. At first I thought I was being penalized for accepting payment holiday in December but I have contacted the call centre & Emanuel confirmed the exact instalment that I also received. He said that my account was in an oversell & explained what that meant. If I understood clearly, I cannot be R599 over with finance charges when I never used the account in December. There is an item I returned to the JHB store on the 8th of December 2017. Unfortunately it was not credited back into my account but paid back. That was an amount of R629. I find it really strange & unfair to be charged so much for the January debit order when my statement clearly indicates the item I return was not credited back but payment was made on the same account. Lately I feel hard done by Game. When will this end? Once I settle my account? Okay noted & thanks for assisting me over the years as one of your customers.
