24 Hours Printing - Terrible service. Best to avoid them.

I ordered business cards from them on 06/03/2024. A week after paying, they informed me that my business cards had not been printed yet and there was a delay because of some missing printer parts. I informed them that I don't want the business cards anymore and that they should refund me. As of today, 17/03/2024, they have not responded to my messages or refunded me.
