problems with casio wk-3300(need help)

[grinchdude]

i bought my first keyboard, casio wk-3300, two months ago and there seems to be problem in a specific part of keyboard although the rest of the keys are completely ok.
the problem is that when i press the keys in that part once, the screen continues to show that they are pressed even when i release the keys and the sound keeps coming.............and sometimes the keys in that part don't even sound. i seriously need help.............. smbody plz suggest something or at least tell me wat the problem is...........................

Maybe you got something stuck under the keys - or maybe the contacts got messed up.

If you bought the keyboard 2 months ago -return it to the store and ask for a refund/repairs/new one
