outage in 61362

Been having trouble with TV  linked to HD Dual Turner DVR for days. Channels in 600s that we want to watch are in Spanish instead of English. HAd new remote sent that would link to TV used all he codes available for SONY!!! can't turn off TV or adjust the sound with remote. Why am I paying for service when your techs can't fix this TV linked to old box works fine. Spent time on chat service with no luck. Service from Xfinity is terrible.!
