I was on Internet and I saw an advert asking for some numbers to check if some things matched. I made a mistake n keyed my mobile no for fun. Next moment they threatened to auto bill me twice a week and there was no way I could stop it. Was some kind of cheating going on. So I had to ask the phone company to block these calls n reverse all charges.
This is dangerous. These days gotta be careful with personal info etc.
Especially Credit card nos., addresses, emails etc
Fraud in "Get Rich Quick Schemes" n Investments are rampant too.
Please Beware.
I really feel bad for what happened to you, this really sucks!
Thus we have no control over such situations, we can only be smart about how and where we choose to share our PI.
