Café Mam review for Orderify ‑ Order Edit Cancel

This app was great up until the last three weeks when it stopped working. I've sent 5 emails to their only customer service contact info and have received no response. Shopify has reached out to them on my behalf and still I've heard nothing. Not a word in three weeks. Meanwhile, we're losing business. I'm wondering if this company has gone out of business, as their website isn't loading either...
