The message said it was the IRS and it said that I was under investigation and to call 06 395 and some numbers I didn't get a chance to write down because my wife was talking too loud.

I'm reluctant to call back even if I did get the number because it may be a scam and I'd be charged a huge sum of money by some sex line in the Dominican Republic.
