Who called from 6128080513

Several call from this person. Claims to be IRS. Then said they were officer John Smith. BS

Left a message, as a matter of fact, he left 3 messages during the same call! It was a recording that kept looping.

Same as above - call is a recording that keeps repeating itself claiming to be the iRS.  Called the number back and they answer as if they are the IRS.  When they started requesting information I advised I know they are not the IRS and that this is all a scam and the party hung up.  DO NOT give these scammers any info.  The IRS does not work this way.

Didn't answer as unrecognized but interesting that it's calling a business extension.

same as the others.  recording stating h is name is David Gray and he want to help.  if i ignore, it could be a federal offence.
