Who called from 2532378075

This number is calling my house.

I have gotten numerous calls from this number and blocked it, but was curious if anyone else has and knows what it's about.

Still not sure who this is, but was on my service providers website and see they are still calling, showed 12 calls this morning before 9:46am alone!
Have the number blocked on the providers site so the calls don't come thru, but still makes me wonder who it is.
Reason I believe it is a scammer is that the SAME number comes in with 5 DIFFERENT caller IDs!!
"Normal" people do not change their caller ID 5 times in a matter of minutes!
