Slow Fios speeds in my area for the last month

Hello,

For that last month my fios internet download speeds in the evenings, approx 6pm to midnight, have been between 100kb and 4 mb. It used to average about 21 mb. the tech support via the phone can see that there is a problem in my area thought they don't know what it is. They say, "my screen shows that is should be resolved by 10 am tomorrow". It never is.

I live in the the southern california area, the Inland Empire. Does anybody know when the problem, and what the problem is, in this area will be resolved? This has become ridiculous and I am seriuosly considering a change of service provider.

Thanks.
