Thanks for your replies,
I don't know if its worth it taking furder action on this issue,but the frustrating thing is i haven't been offered a repaired,a replacement,or a refund,they told me that dust went in to the part and they cant do anymore for me!!
I cant see for the life of me how i could have prevented dust getting in to the part!!or how it could be my fault in any way,
I have asked to talk to the manager about it,he is always too busy to talk any time i ask,they just don't want to know about me really which is making me really frustrated with them,
How much time would i have to put in to teach these people some respect for people if i were to go to the small claims court??
Thanks so much for your advice on this,i don't know much at all when it comes to court and issues like this, as i have never come across people like this before,
