ShipRobot ‑ Shipping Labels

We have had ShipRobot for many years. The app is great - when it works. Unfortunately when it doesn't work, support is non-existent. We've submitted 3 tickets and a personal email in the past 2 weeks without any reply and the app doesn't work, resulting us to have to manually enter freight info. We've had downtimes in the past, that took longer than expected to be resolved, and previously they also had a data breach to which no specifics were given. It's currently not working, they have no phone number to call, so this is the only way I feel we can get any form of attention. Besides a non working app is 0 stars, not even 1. Going to have to start searching for an alternative, or just bite the bullet and direct through Shopify, despite their freight discount not being as robust as ours.

No support whatsoever.
Never even bothered to answer my simple queries. More than happy to charge me for the app though...
Very disappointed. Currently actively looking for a replacement product.

Based on the great reviews from 2 years ago, it seems like they've given up on this app. Zero customer service at this point. Called on the phone (straight to voicemail, no callback after leaving message) and sent them two emails, but received no response whatsoever. Very disappointing. Seems like the app could've worked for me, but it wouldn't let me print USPS labels and I wanted to know how to fix the issue.
