Domain Transfer Gone Bad - Invalid Cert at the Old Host - No Updates At Shopify

[TLF2017]

I scheduled a domain transfer through Shopify after rebuilding our site on Shopify. It's day 14 and we have received no other comms or status updates since the commencement email (checked spam). Today our site (currently hosted at Square Space) has a cert error. The domain is currently hosted at Google (via enom). Name server lookup still shows Squarespace servers. 

I understand it can take up to 20 days but it also said there would be no disruptions. Shopify GUI Admin panel hasn't changed since we commissioned the transfer and simply says:

Your domain, thelucyfoundation.com, is not yet connected
The connection of thelucyfoundation.com is not yet verified. Come back later to retry verification.

20+ days later and still no verification, no email updates and no notifications. Help!
