However I measured the outer diameter of the seat tube and it is 32mm (31.8mm inner diameter I guess)

I found the 2008 invoice for the seatpost and it says "31.6mm/280mm" on it.

So Im confused...I have no appetite to return stuff as I Iive outside the UK and mainly use CRC and Wiggle.

Can someone help?

the invoice might be referring to a 31.6mm seat post clamp - rather than the seatpost itself. If the post was measured at 27.2mm, then that's it
