Lost Gift Card

I lost my Gift Card to the value of R550 and phoned Customer Care Centre on Wednesday 4th February 2015. I spoke to Jeremiah who took the till slip number and promised to get back to me. He assured me that they would stop the card. To date hereof, I have had no response from Jeremia or anybody else. This is pathetic service from Woolworths. At this stage I am sure my card has now been used and I have lost the money due to the bad service of Woolworths. It would surprise me if they refund me.
