Known to happen... 
Right - gut the filter contents & stick your head under the bottom of the oil filter/use a mirror to look up inside it? You SHOULD have a series of six holes in the very bottom of the filter?
Using a pair of GOOD long-nosed pliers open them up and stick the prongs in two opposite holes.
Stick a ring-ended long spanner/wrench on one handle and use the shaft to push the other plier handle round....

Here's hoping this gets your filter out... I had grief with my first filter? Have since swapped to the K&N KN153 filters, these have a 19mm hut on the end to spin them off?
