COMCAST SUCKS

I am having issues with Comcast and their lies. They have gotten really good at it too. I call 1-800-comcast to discuss an amount that I didn't owe because I want service in my name. I had service with comcast over 4 years ago and now they want to tell me that after I went to the office in Sheridan, PA to return my modem and cable box and pay my bill....4 years later I never did any of those things. Oh, but wait, a few weeks ago the cable box misteriously reappeared, but not the modem turned in at the same time....ok FINE I gave up and hung up, then this guy knocks on our door to pitch the new triple play package, we listen and SIGN UP then he tells us that we need to pay $134.00 for a modem never returned...whatever I'm not paying for that I RETURNED IT...then we go to Wal-mart in Robinson, PA, here we find a wonderful woman who helps us, signs us up and then when we call her back to find out what is going on, she tells us that she found this modem and removed it from the account, but there is still a balance of $134.00...ok at this point I am beyond pissed off....I told her they told us that amount was FOR the modem and that if it was taken off then there isn't a balance....she stated to call 1-800-comcast to speak with collections about the remaining balance...I called the number and when through all these prompts to hear "I'm sorry that I can't help you with this account but if you would like to pay for this modem I will take a payment right now" I'M NOT PAYING FOR SOMETHING THAT I RETURNED, I will transfer you to collections then, I am only with SALES....now if you couldn't help me in the beginning then why DO YOU TRY....fine I get to the collections department, speak to another idiot that tells me there is a modem on the account and that it was NEVER RETURNED....I argue this same point with him over and over....we returned this...well there is no balance on your account except for what you owe for a modem....I RETURNED THAT! I ask to speak to a supervisor, after being placed on hold I was told that "I'm sorry I can't seem to locate one right now, I can have one call you back in around 24 hours" DO I CARE TO WAIT 24 HOURS FOR SOMETHING I RETURNED NO!!!!!!!! I called the lady that was at wal-mart back AGAIN and told her what happened and that they told me she was a liar, now she is on the phone with her supervisor, because SHE COULD SEE THE ACCOUNT no one else can see!!!!! old acct #8493100050943641 changed on 7/12/07 to new acct# 899321005285011 which shows that TECHNICIAN dispatched to house 7/2005 and modem returned on 08/2005...NOW WHY CAN ONLY SHE SEE THIS ACCOUNT AND NOT THESE IDIOTS I TALK TO ON THE PHONE!!!!!!!!!!!!!!!!!!!!!!!!! GET THIS MATTER SETTLED ONCE AND FOR ALL....I watched the abc.com live from you tube...COMCAST WANTS MORE HAMMERS BASHING THEIR EQUIPMENT DON'T THEY???????????????
