Received call from this number but no message was left.

why will this company not put me on their do not call list
I have been requesting this for well over 6 weeks now

Um ...
If you tell us the name of the company, perhaps we could answer your question.

Meanwhile, consider obtaining a call blocker.

Received a call from this company.  This is related to another number that called me the other day.  Indian accented man who claims he is from the IRS and calling me about either an audit or back taxes.  I owe nothing to the IRS and immediately knew it was a scam.  The last time they called from the 888 number, the guy threatened to "send the Sheriff to arrest you if you don't pay me via Western Union".  The IRS does not call, you get something in writing.  TOTAL SCAM!
