Add 440-617-5622 to the list of robocalls for supposed discounted natural gas rates, caller ID GAS DISCOUNT.  Other numbers and Caller ID used by this same outfit over the past 2 months:
+11 440-617-5666 (international access digits preceeding the number), caller ID was NAME NOT FOUND;
440-617-5666; ID was SERVICE CUSTOME;
440-617-5701; ID was INFO SERVICE;
440-617-5614; ID was REBATE DEPT;
740-475-2643; ID was GAS DIVISION.
    For good measure let's add 740-475-2650 with ID of HELP CENTER, and same number with +11 international access digits so caller ID was NAME NOT FOUND.  Given the use of same number with and without +11 in the phonied-up call ID, gotta be another of this outfit's numbers.
    What a busy bunch of scum!

440-617-5622  - receive calls everyday - no one there

They keep call my home phone number over and over

Call at least three times per day with recorded message about saving on natural gas.
Two problems - first, on DO NOT CALL list (as if they care).  Second, we don't have a natural gas line to our house

This number calls multiple times every day.  Never leaves a message,
