Any Nader's Raiders left out there to help fight DSL subscribers being ripped-off by Qwest?

Can anybody help me? I am hoppin mad. I paid an extra premium for "high speed" internet DSL ("up to 7 mb download speed"). When I saw no difference in my surfing speed I phoned Qwest technical. They said on regular landline they could only supply 3mb download. 3mb!? I went to a download speed test site and I am getting 2.647 mb download speed--less than their published minimum for high speed on their speed indicator. When I questioned

techs and billing about it, they said they were fulfilling their obligation because they were "providing 70% of their minimum". Oh yeah, says who?? What steps can I take against Qwest Corporation for defrauding customers and using illegal "bait and switch" tactics? Thanks.
