Got the Blazblue TE xbox 360 today, defected button?!

So I bought it for 170 3 days ago, got it today and tried playing ssf4…
figured the LT button (mk) is defected…
it does not register properly… sometimes when i pressed it it has no response at all…
and I tried playing with my frd’s other TE, and figured the buttons dont really feel the same, everything is looser.

Like all buttons + stick are placed lower than other TEs.
Is this an easy fix? I like in the arcades they just replace the button for like $2… Or should i ship it back for warrenty? I bought it from amazon I dunno if they cover warrenty for that. Is there anyway to raise the button+stick upper so it feels its more in place?

I live in Vancouver Canada… and it takes pretty long for warrenty… shipping cost is high too…
got pretty disappointed at madcatz…
Any help will be apperciated!
thanks

i heard the blaz blue TE did have a dip in quality for some reason. there might be an issue with your microswitch in that button. if you want to check the button, open up the top panel and swap the button for one that works. put it back together and try playing again. if the button works now then the button is the issue. when a button on my first SE died i just move one of the buttons at the end that i wasn’t using to replace the broken button.
