Hmm, this guy was obviously using a fake name when he booked. Called himself 'Julius Gonnes' but sounded strongly from Pakistan. Against my better judgement I let it pass, as he was  extremely polite and I decided he just wanted the discretion. He had booked the day before and confirmed early with full address, but no landline.
It was a mid afternoon booking.
When I arrived and had told him which car I was in ( so he could let me into the parking  ) he said he would be " down in 5 minutes". Meanwhile a very skinny, dark skinned Asian taxi-driver got out of his car parked along the street and proceeded to "chat" on his phone for ages in front of my car. Talking in English and the sort of chat a guy has with us ladies. Sure enough, when I tried the number again, all I got was a message to say I had dialled the wrong number - as though he had instantly removed his sim or something
I asked the loitering Taxi Driver if he was Julius but of course he said no, but continued to hang around my car.

Look out for him Liverpool ladies, this is sure to be a regular gig for him.

Moral - no landline? A text photo of a household bill or a bloomin' deposit..

I had assumed the number would remain at ' does not exist' status, so did not include it in my post.

However, just googled it and lots of Indian directories pop up.
Called the number again and he is now answering.

079463469**
Full Number on PM.

Just dawned on me that he probably has phone pics of me sat in my car waiting before he came closer. Glad I wore my huge sunglasses and was in a loan car, but still..   

He called me ages ago to go on a outcall (juneish) there but i didnt make it i was going to suck it and see as i was just on my way home from liverpool and it was literally around the corner but my sat nav started being stupid and wouldnt let me put the address in so i went home instead .
