Billing problem?

Billing problem. So I signed up for a triple play package in the amount of $113.99 per month. So on my current bill there is the $113.99 for my service from 12/2-1/1. Then below it is a billed amount of $59.95 for service from 11/22-12/01. I started the service on 11/22. So how do they come up with $59.95 for 10 days worth of service? If you take $113.99 and divide it out over 30 days (average days per month) it is $3.80 per day. Well if you multiply 10 days at $3.80 you get $38.00 not $59.95 so theres $21.95 I was overbilled. Next there are charges for 1 DVR at $8.95 per month and then this fee is subtracted out since it is included with the service. Below that they have charged me for 4 additional outlet digital cable boxes. Well guess what I only have 3 more TV's in the house and that is all they guy set up when he came was 3 additional outlets...not 4. Those are $5.00 per month per box so there is another $5.00 they overbilled me. Below that they charged me for the partial services of 11/22-12/01 for the boxes..these charges were $1.64 per box and again they charged me for 4. Theres another $1.64 i was overbilled.. Finally there was an upgrade fee of $13.99 and an install charge of $99.00 on the bill for the install and upgrade of my service. Well the saled rep told me there would be no fees or charges to upgrade and no installation charges. Funny thing is under these charges there is a credit for $-74.00 for a service discount. So thats $112.99 -the $74.00 service discount which still leaves $38.99 in fees that i was overcharged. So the grand total of overcharges was $67.58. When I saw these overcharges I immediatley emailed a comcast get satisfaction person whom I was working on a separate internet issue with to tell him of the overbilling. I very specifically pointed out all of these overcharges and he wrote me back and said he understood and that I needed to contact him by phone to correct the billing issues. What? Why do i need to contact him by phone? Well guess what I have tried calling him 3 different times and get his machine. I have left 2 messages and sent another email and have heard nothing back. This bill is due on December 13 and I do not think it is fair that pay the full amount of the bill since there are obviously issues.

He also told me he would refund an earlier service charge of $19.95 i was charged for a tech to come by and try to annalyze an internet problem I had been having. The tech found no problem and told me it was a router issue. Well then the install guy that came by to do my service upgrade about 2 weeks after the 1st tech came by found a wire problem out on the main line under the street. So yeah that original service fee needs to be refunded as well in the amount of $19.95. i was told this would be done but of course have not seen any action with that either.

I STORNGLY RECOMMEND THAT EVERYONE WHO HAS SERVICE DONE OR SERVICE UPGRADES CAREFULLY REVIEW YOUR BILL. MAKE SURE YOU KNOW WHAT YOU ARE BEING CHARGED FOR.
