This seems very 'scammy' to me. Scary too. I've just received the exact same letter from Tower Investigations at my home address, but to a completely bogus name. I open ALL letters correctly addressed to this house, even if they don't have my name on them. The only return address on their letter is: Registered Office: 2C Cartwright Court, Bradley Business Park, Huddersfield, HD2 1GN. The only phone number is the 0800 number in the text of the letter. They also show: Company Registration No 03402831 Consumer Credit License No 565360 E-mail: [email protected] Website: Tower Investigations The only contact details on the website are the registered office and the e-mail address, no phone number. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (to cut a long story short) Several years ago I started getting letters to this address with a different name. The first three I sent back "Not at this address". But they kept coming, so I opened one and found it was Inland Revenue claiming unpaid income tax (to this bogus person with a different National Insurance number). I telephoned them and explained this person doesn't live here and never had. They apologised and said 'ignore the letters", but they kept coming. I phoned several more time and wrote them a letter. But they kept coming. I saved about 20 of them and posted them all back in one envelope with a nasty letter. But they kept coming. Eventually I had the Bailiff turn up at the front door looking for him. I explained this person doesn't live here, nor had he ever lived here, and it all stopped. UNFORTUNATELY, not before a CCJ had been levied against this address by the Inland Revenue. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - I've already had a couple of letters addressed here to this new bogus name (which I've dealt with), and it's my guess that Tower Investigations are trying to find this latest [EDIT]. I tried phoning the 0800 number, but all I got was an automated message which 'claimed' to put my call into a queue (with a very strange ring tone). I'll try again on Monday from a public call box.
