I ordered poster printing before, I made a data as their instructions show on the web site, but the printing quality was terrible.
Found out the format(or settings) they show doesn't work well.
I asked for a refund or to redo.
But they responded a week later, which was too late for the event I participated.
Because of their massive delay, I needed to order the same thing at a different store.
A customer support was rude too. She even didn't apologized for their mistakes. No refund.
Not an honorable / trustworthy company.
