On the basis of what little information you have posted - the most obvious answer to this question is YOU !! 

You've eluded to the 090 number, the Belguin number, the company's website address, it's postal correspondence address.........

Thanks. That is helpful indeed and has lead me to the underlying geographic number to UK telephone number 0905 60 95 609.

It is a pity that the OP didn't furnish us with more information and expected us to fathom this out for ourselves.

Indeed, I called the 0905 number and found it is answered by a sythesised female voice. This is the exact same female voice as is on the number published for after-sales service or web helpdesk, +32 (0)2 723 23 62. This is a vital pointer that has thus far not been picked up on, and tells us that the number is answered in Brussels.

I then simply went through numbers, changing the last couple of digits, until I found +32 2 723 2338 which is answered the same as the UK 0905 number (and is thus its underlying number). This is a Brussels geographic number (the area code being 2).

It's probably best to use a provider like 18185, rather than your line provider such as Virgin Media or BT.
