As has been said by many others, forget about her and move on.
I actually had a similar scenario (except for the creepy change numbers thing). Very convenient SP for me that was a good provider and would book at least once a fortnight if she was available, although some personal details were exchanged, I didn't ask for any. There were a couple of cancellations by me and similar from her.
After 6-9 months I got no reply for a couple of weeks running, first was for a short notice booking that wasn't likely she'd be available for, next week no reply for a booking later that week, so I decided that for whatever reason, she must be blanking me. Was about to move on, but thought, unlikely but possible she'd lost her phone or whatever, so I emailed the next week asking if she had any availability, and recieved a quick reply with days and times.
I text asking for a time and date that was on the list and was told she had no availability and should maybe look for someone else. There was no attempt to hide my identity, but she obviously didn't connect the 2. And I had my answer. Still no idea why which as someone says is irritating as if I've done something I'd rather know so I can avoid it with others. She may have suspected EAS (frequency was more due to the convenient location,being a good provider and reasonably priced), I just thought I was being considerate not talking about other SP's while I was getting my dick sucked.
No good can now come out of your situation and I would suggest that you never contact her again. It's not like you punt in a place with a lack of choice.
