Who I have the same questioned this topic

I switched from another carrier as had  a lot of dead spots and now with Verizon i  have a lot of 3G . did not know anyone still used this 

Call verizon was told something like towers are overloaded and you are bumped to lower speed and asked what is plan to upgrade towers and was told no one knows (asked rep if i could talk to anyone in Verizon and she said all will tell me the same ) 

I was never told this would go to 3G?

Anyone else have this issue in Estero Fl  and other areas in Fl
