sales rep sales pitch too good it's BAD now!

ok. the other day a comcast door to door sales rep was walking around on our apartment community trying to "win" back customers who switched to Verizon Fios. His sales pitch to me was the triple play package with digital preffered, starz and 6-months free HBO, free HD/DVR for a year, "the fastest internet available that they offer" (which would be 50mbps) but I think he meant the 16mbps service cause I highly doubt I can get the business class internet with that, and unlimited phone all for $89.00/month plus a $200 rebate check and a $50 referral credit for referring my Mother-in-law for signing her up too. I informed him that we currently have a past due balance of $167.00 from last year and that we couldn't sign up anyway. He told us that Comcast is offering a "fresh start" program and is forgiving previous customers their past due balances if we sign up for the triple play. I said ok because I was not happy with verizon fios. He took my and my husband's info and said that he will call the next day with an install date. He called the next day to let me know that he couldn't get us the triple play because we have a past due balance but he could get us a double play (same specifications as the triple play for TV and internet and with a $150.00 rebate check instead of the $200 and would still get the $50 referral credit for my Mother-in-law) with just my driver's license number, no SSN needed. So I gave him the information he asked for which was my name as is on license, license #, and maiden name. He called me back within 20 minutes giving me my install date. Well that was yesterday and this is what I got....Digital starter package for 39.99/month (no starz or HBO), Economy Internet package of 1 mbps download and 384 kbps upload 27.95/month, and HD/DVR 14.95/month. I noticed right after the guy left that we didn't get the channels he promised and I did call to have it upgraded to "classic" for now for an additional 12.95/month for a total of at least 95.84/month plus all the taxes and fees on top of that. It don't end there. When I called Customer Service to get the "digital classic" turned on, they had a hard time verifying my accound because the sales rep used my middle name as my first name and my maiden name as my last which he spelled really wrong. Unfortunately I didn't write his badge number or whatever down but I got a Comcast Subscriber agreement on which he filled out what we were suppossed to get on the original day he showed up and signed us up. I already cancelled Verizon Fios, of course except for the phone service, since we "couldn't" get that and I called the sales rep (which I do have his phone number, i beleive he is a subcontractor since the area code is from buffalo) and told him what happened and he said he will TRY and fix it but since he switched around the name and he is not me, he isn't sure if he can fix it, but he will talk to his supervisor, or so he says. Where the heck am I suppossed to go from here?
