I am trying to cancel and get refund

I have been trying for 10days to install and won’t work. Please consider this my cancellation and request for refund. I’m very surprisedthere isn’t anyone I can email or call to make sue they aren’t stalling as there is a 30day window. I want to speak to a person or on line chat.
Thank youNOW I’M BEING ASKED WHAT I WANT TO DO WITH MY MESSAGE. I want it posted I should have read reviews.
