Incorrect Information and poor service!

I had recently opened up an account at Game/RCS. Had a week ago purchased a few items for a large amount and after an error with the transaction requested it be reversed which was done in the store. Upon reversal was advised that transaction would be successfully reversed and amounts reflected within 48 hours(2 working days).<br> <br> This has not been the case and after a conversation with agent(Vuyiswa), who had displayd no concern or understanding of that matter, was told reversal amoount would only reflect after the 10th?? After requesting a line manager, was placed on hold for ages and resulted in me needing to terminate the call.<br> <br> What is the reason for the poor service and great misunderstanding with the call centre staff? And why would it take so very long for the reversal taking so long to be actioned?
