We get alot of these calls all of a sudden. They try to get us to push any number by a recording saying if you want your number off the call list push any number, to speak to a customer service rep. push any number, this calls pertains to a serious business matter please push any number and so on. We have been getting alot of calls with legit area codes, but the next 3 numbers are all zeroes and when I called the phone company they stressed do not punch in any number at all. Hang up and then pick up the phone, if you have a dialtone punch in *57 to activate call tracing. but do not punch in any numbers until you have that dial tone. What a pain these calls are.
