Nike — nike air max 95 trainers

Dear Sir/Madam, I am writing this letter in regards to my customer rights. On the 9th of April 2009, I purchased a pair of Air Max 95', for £110, and for buying such an expensive item of footwear you expect them to last a long while. These were bought from JD Sports Burnley, branch - no 111. After just 2 weeks of buying these trainers I noticed the air system in the heel of the right trainer had popped. Due to this I returned the footwear to JD sports, in the box with the receipt. I was then told by staff that they would have to be sent for inspection at JD fashion PLC, (customer services). So I agreed for them to be sent off for inspection and was told I would hear from them within 2 weeks. 2 weeks had passed and i went into JD sports to check on the progress. It was then when I was told that the trainers could not be refunded or exchanged. I did not want to be refunded, all I wanted was a pair of trainers that were not faulty. To me, the services I was given seemed less than HUMAN. I was given the trainers back along with a letter saying that the damage was down to wear and tear, which really is impossible due to the fact I had only had the trainers for 2 weeks. I am sick and tired of being given the run around. I have been advised to take legal advice and take this matter further. First I wish to ask you for your help in solving this matter as soon as possible, as I have been pushed from pillar to post for too long. I would appreciate all your help.
Thanks
