***** case.....what a joke!!!

I picked up some activity on my acount about 4months ago. I went to Nedbank and opened a case. They issued me with a new card and told me it would take 8 weeks which i knew because this has hapened before. After 8 weeks i went to the branch just to find out that my case was never even logged by the first guy that assisted me. I was furious! A lady then phoned the ***** department and told me they will contact me. I got a call from the original person who assisted me when i went in to the bank to log this. He stated that the Mystiqe beaty account is the account of my local supermarket. I told them that why would i swipe my card 4 times after each other at the same place? It doesnt make sense. I did not believe this nonsense so went to my local supermarket where they confirmed they have never heard of such an account. They also would like proof from Nedbank stating that the account belong to them. In total there were about 9 transactions. I would really like to get the evidence from their so called ***** department.
