Poor service with motorcycle purchase.

In February this year I purchased a Big Boy TSR250 from Motorcycle Junction(and/or JP motorcycle repairs)in Brackenfell. I was assured that everything was in order with the bike and the documentation. On trying to get cor it was discovered that the engine number was different to that as on the papers. When I contacted JP at motorcycle junction for some clarity, he promised to come back to me, well that was quite some time ago and I have not heard anything back. Further messages have been met with silence. Needless to say I have been through the whole process of getting police clearance(which is a mission) and have finally been able to get it cor passed and licensed. Bottom line- if you buy a bike from them do not trust that all is well. Check the papers to the bike and ensure all is correct as obviously not everyone is truthful or forthcoming. Had it been mentioned upfront a lot of hassle could have been avoided.
