I've been using Holy Grail Nails since September (I think I posted about them). Never had a problem, wore well, delivered fine etc. They encouraged ordering via the app. Bought 3 sets. One fine, the other showed grey when delivered but I had bought white, and the last were black glitter, I had wanted black gloss. Contacted customer service, she asked for feedback on the app, so I explained (politely) that it wasn't as clear as you can't zoom in so I couldn't see the black I ordered was glitter. I had the rudest response and when I wrote back and (again politely) explained I was upset by the response, she said I wasn't happy with my products so send them back and get a refund (not as polite as that). I explained again that one set I was fine with, the white ones she had explained although the packet colour is grey they are white (odd but fine), so it was just the fact that using the app I couldn't see one set was glitter.
I am left shaken by the poor customer service, it really impacted my day and evening yesterday. I asked to speak to a manager but of course no reply. I know it sounds silly, but it was so completely uncalled for and unprofessional.
If anyone can recommend any similar products (I used the ones you cure under a lamp, not just the stick and go ones), please do recommend.
