ENGEN FLORIDA GOLDMAN- POOR SERVICE REFUND

My son purchased a packet of cigarette at the mentioned convenience store this morning. Prior to that their system had to be restarted after my son already swiped my Nedbank card. He was requested to swipe my Nedbank card again. I have received notifications via sms that I am charged twice for the same transaction. In addition my son was not supp**** with a slip at all. I approached the mentioned Convenience Store with proof of the transaction notification and I was told that I am required to supply a bank statement in order to receive a refund. Firstly it is a requirement to ensure that e****ent are fully functional to serve consumers and also the the right to of a consumer to receive a copy of a purchase slip and above it all not suppose to cost the consumer money by being required to obtain statements.
