Disappointed with service

After a long day from work my college and I went in at clicks east rand mall to get refreshments. I told my colleague to get a buddy bottle a stoney in flavour while by the door I opened it only to be welcomed with a strange taste only to realise it was zero. I went back inside and requested a stoney original and explained that this particular one at hand was taken in error but the guy who was called in as a manager said that was my problem as I took the product off the shelf myself. So I left it there even though I had only taken a sip and it was clear that really an error had occurred. I have always liked shopping at clicks even for my medication but after this episode I would rather go to Dischem . I was really looking forward to that drink especially as in my pregnancy I crave such drink. Very disappointed with service received.
