I believe this is a scam, there have been a number of them with the same features-
MILF, although this one is the oldest
Zero feedback
Suspiciously cheap rates
Ask for calls only, no texts
When you call, goes straight to voicemail
Profiles don't last long but are replaced by new ones that look the same
Another one at the moment is Rita-40+
Not sure how the scam works, what are they using your number for?
