Trevor, who owns Trevor Bell Construction Limited, recently changed the name of his business and had notified HMRC of the changes.
But each letter stated that 31-year-old was in arrears with the company and that he had to pay the tax for the sub contractors he employed.
As soon as Trevor alerted HMRC, they admitted the mistake and they said they would put it right.
Three days later Trevor received the apology, those of us who are familiar with the dealings of HMRC, might have both feared and expected.
He received a further 90 letters, all stating that he owed nothing!
