Not a prank call!!!
The people are scammers big time!!!
They call from these fake numbers so they can't be reported.
If you do answer they say some amazing carpet cleaning deal
or credit card offer. Then they ask for info and prepayment.
Report show They're doing three things;
1) Never show up and no way to get ahold of them
2) If you don't pay them up front or won't give info up front
They ask for payment when they show up and clean with
just water.
3) They have been reported to then steal your identity and
charged stuff to the card they have.
I'm sorry to say, now that they have your # expect up to 7 calls a week at times, then 1 call here and there for a couple months, repeat.
Good luck
And remember don't ever give any stranger your info!!!
