time warner cable/spectrum spectrum they're ripping me off for $370.28 which I don't have Overland Park Kansas

I am a 63 yr old disabled senior citizen living a on a fixed income Section 8, & Food Stamps. Time Warner's the only cable company available out where I moved to. I don't understand their billing system. I First of all they had to send a tech out here for something for the first 3 weeks I was here. Then they told me they weren't billing me for it, but the did at $40 a pop. I've recently made payment arrangements for it of $217 to be paid on Jan 3rd & Feb 3rd to catch me up. Today I get a phone call saying my service is in danger of being disconnected & I either need to pay $213.72 or $370.28 to prevent the disconnect. i am fed up with this crap. I'm going to the hospital Jan 11th to have hernia surgery...I don't need this headache. If they can't accept my payment arrangements, then what do I do for Internet & Entertainment? I have no car and I'm in a wheelchair. Please advise.
