United States Trademark Registration Office Deceitful attempt to look like an official US Agency and bill me for $395.00 Los Angeles , California

I am in the process of registering my name as a trademark brand;
I used a lawyer to go through the process and he informed me that all fees necessary had been taken care off but that i will receive deceitful mails impersonating official agencies, claiming that additional fees are due for the ongoing process.
The United States Trademark Registration Office is so far and by far the most deceitful one i received;
not hesitating to refer  to the US Customs and border Protection agencies, the Homeland Security Dpt.
