hard to get a close shave must press supper hard against my face.

This shaver is easy to use but a problem has developed this past week shortly after my 30 day window. the shaver cover will not flip open. initially it worked fine however now I must hold the button in and take my fingernail and open it so I can clean it. I would like to ask the supplier to replace the front shaving head to repair the "flip cover". I am concerned if it continue to degrade, and will not stay closed, i won't be able to use the shaver. Please Help
