dish did not leave contract with me so I could see the facts would not send rep when needed and overcharged what contract calls for monthly anddid not retract

I am 89 and contracted w/dish for 2 years and did not understand that if am dissatisfied could not get tech out to help w;tv and would not explain extra charge over my contract and refujsed to answer my wuestions re service  --they lost 2 stations including abc and did not advise until it happened and so my watching tv on those  stations was not a credit to my account---hopper did not work correctly and no tech  theyjust kept telling me wht to do and at 89 cannot follow their instrutions evidently
