Hooking up a new xumo & remote to my tv

My xumo & remote stopped working...it's only a few months old. I called C/S twice and just received a new set. I need verbal assistance to get it up and going once again. I have been w/o TV for a week now and would greatly appreciate assistance. Please do not link me up with AI - I sincerely dislike AI. I need a Live Agent to help me.  Thank you.
