Greenstone apalling service

Your Greenstone branch has absolutely appalling service, its not the first time this has happened, not a single customer is happy with the service at greenstone Vida. Every other Vida stores will make your order if it is not on display, this is the only store that refuses make anything that is not on display. When we want to use our discovery vouchers, everytime they would refuse it. Today was the most ridiculous, they refused and told us to go to another store that would take vouchers, and even hurried us out of shop giggling. Very arrogant, extremely rude. THey would make remarks such as "why are you still here, why dont you just go to another store with your vouchers?". We have complained on hellepeters and google reviews on multiple occasions, never get feedback. The staff at this store will close down the place eventually.
