Poor business ethics

I was at the pavilion kiosk ,were i did a refund on the 30/11 .i was told that refunds are done on a friday which after sometime i accepted and told them proceed however till date i have not received my refund last friday passed and i did not even receive a curteousy call .very poor business ethics !!!totally digusted with their service its like they want our money but when its time to give money back to the customer it becomes weeks of waiting for money that belongs to you! Disgusting service right till head office!!!
