Bittrex sub contract part of the verification process I think. I also was able to pass, bit upset that I dont remember receiving an email on the issues but at least it was possible to resolve the problem after the fact with some effort.
I have also since contacted them to change my details, again required more use of a government photo id and contact over a week but it was done.
The last issue was with ETH deposits which were not being credited, this has taken over a month but the last deposit did dislodge all the parts made previously so that too has been resolved. Just calling it how I see it, obviously peoples experience varies but I hope it also gives some hope to anyone waiting that they do work through issues. There are worse companies out there to be bound to.
