Avast premier, 2 years license doesn't work

hi everybody, I know I’ve posted this before, but nothing of what i’ve tried has worked.

I bought a year ago avast premier for 2 years, but now I get a message that expires in 16 days and asked me to buy another license … i’ve tried clean installation, and download again the license, but license has expiration date of 07/28/2015

so my question now is, there’s a way to contact the company? what should I do now? they charged me two years and gave me just one.

and then again, sorry for english mistakes, and sorry for posting this again.
