the reply; I don't do contact via phone, only email. That's a new one; a WG without a phone.
I've had 3 bookings that were done solely by email where the WG either told me her "work" phone was broke or she didn't have one yet... One WG I had two bookings with and never got a number so both were done through email right up to booking time

Don't know if she ever got a phone as never seen her again after 2nd booking...
The other one gave me her full address, including buzzer number the night before the booking... I had my reservations, but the booking went ahead... I advised her she should get a "work" phone as this probably wasn't the best idea going fwd, as it appeared to be her own flat (according to her)... About 20 minutes after the booking I got an email giving me her number.... She must have went out and bought that phone pretty damn quick!...

That's not to say the one you've linked isn't dodgy as fuck though...
