Right where to start, i am ahving a prob with a trader on this site which i wont say who yet but want to know if i am out of order?

It all started on the 27th of April when i ordered some car parts sent the money via a cheque. One month later i pm'd him from here and he said he was having probs getting hold of some bits, fair enough i thought carried on waiting it got to two and a half months and i had enough so when he said he would send me my money back i said yes to it. This has not arrived yet either its been over 3 months now and nothing i have pm'd him between 15-20 times and he has replied but with no actions. I got in contact with trading standards about it and they said "if someone does not deliver the goods within 30 days you are entitled to your money back" so i have written a letter to him stating this and i have heard nothing back. Now i will take this all the way to court to get my money back but its hassle for me and him plus he would have to pay for my expenses loss of wages travelling to his area for the court day it will cost him more.

So am i being out of order??? I did not expect this from this man.
