Claim Vitality rewards incorrectly

We went searching for a Kauai and finally found one at the VIRGIN ACTIVE in Milpark. The service from the lady working after 18h00 was despicable. She was not interested in helping us, infact she didnt want to assist us at all. We had cell phone reception issues as this Virgin active is way under ground, we couldnt download our BARCODE but clearly showed that we have received rewards & chosen Kauai. It was so embarrassing and disappointing to stand in front of a queue trying to get help from this lady and all she did was laugh at us. Her colleague downloaded the one barcode that was saved on our wallet and when he said he would make the shake, she came and took over the till. she re-entered the barcode and said that it had expired. Without hearing her colleague (who wasnt very helpful in our defence) said that he had entered it, she then said, no it has expired and was dismissive. Even though this is a small issue - this is unacceptable. We drove around looking for a Kauai and when we did find one - we received this issue. Its disgusting.
