Cox Ultimate - getting 60-80Mb

Same deal in Hartford, CT. Consistently getting 30-35/30 and support does nothing to help. Twice they rebooted my modem and suggested they send a tech out. Running a CAT6 direct and still getting one tenth of the download speed I pay for. The best part? I just upgraded a tier and its now worse! Really considering switching ISPs if Cox can't follow through on these speeds.
