Boostmobile Unlimited service Irvine California

I think we should bring about a class action suit and sue Bosstmobile and its affliates.I have gone around the world and back to the Phillipnes to  the U.S., with no resolution in calling the call center speaking to incompetent phone personnel.I have no service in the 90044 area code since purchasing this phone and  plan. In the last 8 months I have called called and called. I asked to have a Hotspot to resolve the issue over a month ago ... to no avail. I initially signed up for unlimited web, text and talk over the course of timesince having this service it is no longer unlimited web as the monthly fee drops so doe the lack of unlimited web usage...I was told just this month of June that my service was restricted because I went over data usage...a real joke. The poor phone quality is totally ridiculous the calls drop when at home half the the person can not hear me...I asking can you hear me now (no). Sometimes I can get service after midnight some nights but I work days, its really stupido. Is it legal for a company to have no oversight or corporate phone number for customers to call?
