I wouldnt have a wank about it yet
Maybe I am cynic but the amount of times I have met alleged Indie's who give you 'there real number' because they do 'specials' so they can set up meetings without Winston or Kevin finding out is quite large
Quite often, these are not "real" or private numbers. It is their 2nd AW Number, which has not been displayed in their profile. They are aware of loads of timewasters call on their "normal" AW number, so once they've seen you and sussed you out, they elevate you to the 2nd AW number.
This way, most calls or texts received on this 2nd number are genuine, and from previously seen punters, so not many texts enquring about services, availability, etc. Even when their normal AW number is not displayed or it is switched off, their private 2nd number tends to be on, as they know there is better cahnce of getting real bookings from there.
