What is the best verification method to use.  

Reason I ask is that after one poor performance by a provider I submitted an honest review, and no supprise that she gave negative feedback when needing a referal.

I don't know where you are located but some of the Escort Agencies will also act as a referral service for you. TVI Girls for one.

I also tell my potential providers I am a VIP member of TER and that they can look at the posts and reviews I have written.

In addition, I give them a list of the names of the various providers I have seen in the area.

It is rare that I get off the phone before the providers agrees to see me.

Don't expect a provider to give you a referral if you ding her even if it's honest.  That's just being naive. Assuming that by verification you mean having a referral for a provider who requires one AND assuming that you're fairly new to the hobby, all I can suggest is that you providers that don't need one.  If their service was satisfactory than ask them if you may use them as a referral.  Many won't but some will.  Otherwise, explain to the provider, who wants a referral, that you're new and can you provide alternative info such as employment contact number.  Don't worry, they'll never call you or rat you out; it's not in their interest.  They just want to verify that you are who you say you are.

... or, get the referral (and your next appointment)  BEFORE  you post that negative review ...

Best verification method? For yourself? Your post is confusing to me, sorry! If you're referring to using a lady you've recently seen as a reference, that depends. I prefer a gent to ask me in person after a second visit (at least) if I'd be willing to vouch for him in the near future. I just ask that he give me a heads up that a Lady will be contacting me. Many ladies aren't fond of being used as a reference and some refuse. Be sure to ask beforehand...unless you want a negative reference! Im thinking, tho, if you wrote a negative review of her, I can't see her saying anything Positive about you. If the session was truly BAD, why would you want a referral from her in the first place?

Check into some of the Client verification services.
