A Google of the fax number without a space in the local number, ie
"01925 837780", reveals nothing. A search of
"01925 837 780" reveals 1 hit on 192.com which is for the fax number of a company called Furniture Management Services Ltd, TRIDENT INDUSTRIAL ESTATE RISLEY WARRINGTON CHESHIRE WA3 6AX. This was cached on 21 May 2007 and the telephone number was 01925 820 556.
On the same 192.com cached page, there is another company shown at Trident Industrial Estate with a similar name: FMS (FURNITURE MANAGEMENT) LTD, tel: 01925 822 247 fax: 01925 826 068. A search of 192.com today shows these two companies, but both have these latter phone and fax numbers. So perhaps Moneymatters has only just (within the last couple of months) aquired the fax number at least.
A search of 192.com for companies at and near the post code quoted by AVNM shows Moneymatters Nationwide Ltd with the phone number (no fax though) quoted by AVNM.
Does the company have a website?
