Levi's
Size marked incorrect

Bought a pair of Levi jeans over a year ago, bought 2 pairs and now finally came to my new pair of jeans, pants are clearly marked size 34 and when i tried it on its meassured a size 30 jeans, the store gave me attitude and said its a year later and how could i mis the diffrence in size, I DID NOT WEAR THEM until now present day, why should i spend so much money on clothes and now that there is a problem no is there to assist, i understand the Markham store as Levi are only sold there but now i am stuck with something that is clearly a Levi fault, and what was told to me in a snotty remark is contact Levi, i would like my money back or new pants
