yes that is one issue, I had a near scare the other day, tbh was my fault if I contact a escort I tend to block the number after so the cant send soliciting txt or calls like I missed your call three hrs later. but booked a home visit but never dawned on me I had blocked her number from generally inquiring the week before, but had to give my land line on booking .i did the booking but she could not locate address tried ringing me and even rang my home but had gone to shop, so I waited but no sign tried ringing her no answer then phone switch off, found out later she could not get hold of me then I realized why. had left for work but luck had it she never left a msg on machine. phew
