Transactions duplicated on account.

I ordered some books from cna as I am a student with a very busy schedule . Goods was received in good order and everything till my newest Edgars account came reflecting the same transaction twice. I phoned online purchases department and was told that there were a ditch in the system at the time and that they will rectify this.<br> <br> Nothing has been fixed till date and I refuse to pay the additional R240 as it is not for my account it is duplicated. Today I visited Edgars stores to pick up something , I was told that I cant buy because I need to pay an additional amount of R 204 - This will not brake my bank but I will not pay it as it is not for my account.<br> <br> Edgars and cna group just lost a very good client of over 10 years , i felt humiliated in front of a queue full of other customers. <br> <br> I want a written explanation and my good name back ... I will not let *********** staff and a pathetic system ditch throw away my name. <br>
