Unsatisfactory service by Sorbet Menlyn

I went in at Sorbet Menlyn to buy a gift voucher, the lady who assisted me was very rude and unpleasant with her facial reactions, however I ignored it. Told her I want for a hot stone massage and she said they don't have that, but asked her to confirm, which she did and she was wrong. I then purchased the voucher, gave her my numbers for loyalty pounts, to my suprise when I tried sorting out the gifts, the voucher slip had a name I know not of 'Angelo' as the person who purchased the voucher. That was so unprofessional of her.
