A possible solution: I have been complaining as a Comcast customer who is not getting his emails. Today I was contacted by the Comcast national abuse team. They said that anyone in Belize having this problem (not sure how you are supposed to know)can call Comcast to fix it. The number to call is 856-317-7272 between 8:30AM and midnight eastern time Monday through Friday or 10AM to 7:00PM weekends. They asked me to send the information to people I know who are experiencing the problem. They said an alternative to calling is to submit the form available at comcastsupport.com/rbl
