Who called from 2192136960

This number keeps calling me

Wanting to buy the stove I just posted on Craigslist.  She ask the location and if I have a paypal account.   I responded its in Vancouver and Cash only.  I never got a response after that.

Same thing on the paypal, told her cash only and that was the last I heard from her.

Got text asking a if this was a legit post and if there was anything wrong with it,never got a respond after i wanted full price

Someone is trying to buy something from me and their number is 219-213-6960
I Google it and it's a spammer from Gary IN
I already gave my email and name
What else can I do know to protect myself?
