Yes. I had trouble. I made a booking, then cancelled it, because I got a much better offer with a different girl 15 minutes later. So Luisse blocked me on that number. I got a new sim. Luisse ignored that one. I got a different sim and got lucky with it. I was cycling through sim cards regardless because I reckon that some girls just block you if you don't follow up an initial inquiry with a booking that same day.
Sim cards get stale and I lose track of who I pinged with which one.
