Try your State Attorney General’s Office and report it to them.
They may be able to help put a stop to it.
Give them a Call most of the AG Office's have a Toll-free Number

Keeps calling and when I answer says: "Goodbye"  Can't block cause phone company does not recognize it as a valid number they said it is a "spoofed" call.

I have been getting a call every weekday for last week , usually around 9am.
I did not answer cuz I don't know this exchange 059  or any one w/this number.
Decided to search this #  this AM- Glad I didn't answer. I am also registered on the
DNCL for my home & cell. Get telemarketing calls all the time on my home phone-
this is the 1st on my cell.

I get the same call I say Hello and they say Goodbye--3 times a week on going what can we do !!!

Call the FTC. Have a list off calls dates and #. They get an $1100.00 fine 4 each call if U are on the DNC list. They will then stop calling 4 a while, but then start all over again.
