The first thing to do as a Gmail account holder (while dealing with any Gmail customer service issue) is to visit the Gmail Help website.

Gmail Support Forum

If you do not have enough time to read and fix things yourself, then you can access the FORUM of Gmail Help and post your problem(s) there. Gmail experts and users might post back an answer to fix your issue. This is very time-consuming though.
