Early termination of contract fees

I signed a 2 yr. contract with Dish Satelite and after 12 months, my rates went up higher than I could afford.  I am 86 yrs. old and only have social security as income.  I was offered a bundle with another service and went with them.   I paid for sending the equipment back to Dish, and they say I owe $260 fees for the extra year that I didn't keep.   Can they make me pay for this?  They sent a notice that they would be deducting this amount from my debit card- bank account at the end of June.  After paying my other bills, I don't have this much left over.    Can they sue me or make a lot of trouble for me?  I am not well, and this is worrying me.  Would appreciate your advice.
