Right to choose

I was speaking to my GP regarding waiting times for diagnosis and he mentioned about the "right to choose" , I emailed one of the providers a few questions and received a cut and paste response to check out their website, which didn't answer the questions I wanted answering.

They were very keen to mention that I could go privately and pay £2300 and be seen within 7 weeks.

From what I understand that these services are predominantly video calls and online questionnaires. I don't like video calls or phone calls and avoid them if at all possible.

Does anyone have a recommendation (if allowed) of providers as the NHS wait is starting to wear heavily, I've been on the list for over 2 years and it could be another 3 before I'm seen.

Thanks
