I can’t help I’m afraid, it’s really hard to verify who’s legit and who isn’t. I would try and work something out with the provider.. I just searched telegram for ‘vaccine pass uk’ or some variation of that and then started reading through comments.. good luck anyway, I hope you find a solution, and if you do try it out locally (somewhere with no consequences first). That’s what I’m going to do if it gets to the point of no return.
