I placed an order on December 7th 2019, it was $65, which I had purchased and used a Groupon for. I received an email stating my order had been placed. Around December 22nd I realized I had never received a proof to approved, so I tried contacting them, when I go to their site (everyday since Dec 22) it says the site is under maintainence and will "be back soon". There is no number or other contact information at all.
