Flyclothing LLC review for TikTok

We've been in business for over 22 years and probably have about 20 apps in our Shopify store. We advertise on every medium possible. We've never experienced so much difficulty or lack of support as we have with this application and regardless of what information we supply to their "support" team, we get no resolve. They want social security numbers, Tax IDs, all locations, all application information, etc. I just counted over 200 emails to support requesting assistance and support continues to provide circular and repetitive unhelpful responses.
