Who called from 3475022582

Credit card rate decrease.

My mistake.  It was from Duquesne Light about electric rates.

It is not actually Duquesne Light, it is a company trying to get you to switch your electric supplier to them.

347-502-xxxx (differing ending digits).. calls at end of month, does not leave message. Often calls 8:45 a.m. or 8:00 p.m., sometimes multiple times per day, if it is end of month, as 27 - 28th of February.

Call blocking, so far, has not worked. Telemarketer has dialed our number a dozen times since January 2013.

I answered the 20th or 30th call from this number and requested we be taken off their call list.  The "lady" on the other end hung up on me and the calls have continued.  Anyone know of a device you can sound into your phone once you allow a human on the other end?  I'd like to damage an eardrum or two.
