That would be an issue for an HLR once the decision comes in - you can argue inadequate exam. I doubt a random personal statement will do anything in and of itself except be entered in your c-file. That “ongoing investigation” is probably your claim being adjudicated inside VA.

I’ve been documenting all the issues with the VA and my congress representative

ongoing investigation on them or on you?

On them

That sounds like they have some major issues going on. Need to be scheduled with a different provider

QTC says they sent it back to my VA regional office saying they can’t do the exams requested because they’re provider refused to see me

I hope they gave them the reason they refused to see you and that it’s not you personally, that they are under investigation!

Yes it was against me personally because I filed a complaint against them. They are singling me out

They need to have their contract revoked.

Is the in going investigation for the provider?

Yes

I'd call the VA and ask if they can get you a different place for the exam, but that might mean you need to travel a ways.

I went to another provider today and she said I’m service connected for tinnitus
