Same thing happended too me. I received a call from 888-477-7798, answered the call and no one was there. The next day I (Today) I received 2 calls from 425-390-8933.
Got a call from 888-247-7798 and they didn't leave vm and I got a recording stating the # "could not be reached right now and to call back later". I just received a call back from this 425 number and the caller stated they had "missed a call from me" (which is totally BOGUS). They are SCAMMERS!! and say they are calling people who owe $10k to the IRS (which, I DON'T!!). Told them my # is on the NDCR and not to call back ...... she started getting really snippy and I hung up.
