comcast cable xfinity this company been ripping me of on my cable service calls when problem is outside of the house schaumburg Illinois

comcast has been giving me poor services for years with my cable high speed internet and equiptment with outages and connection problem every time i call them to report a service interuption .I'm getting charged with severioce call when the problem is out side of my residence and these tech dont know what they are doing they keep lieing and saying that the problem is inside when it the oppset of  .I'm sick of there huge bills for problems i'm not responcable for i depend on my service and tired of it always going out and fighting with customer service agents .About not getting my bills on time i'm getting charge for two months of service  and them chaging me past due amounts with additional charges .

I'm a senoir citizen and comcast is ripping me off big time ive had my fill comcast is the biggest rippoff the techs admitted that the problem were outside related I feel i'm due some justice here.... and they slapped me with a $500.00 bill and shut my service off when i was suppoes to get credit for 5 weeks of no service  .And i feel i'm intitled to more than five weeks of bad service when this has been going on for years and they wont cancel my services when i requested it they hung up the phone on me they are the worst....
