This company is not serious about their customers!!

I’ve been waiting for my panic button for almost 5 months now. I’ve sent numerous emails to which I’ve never received any response and I’ve called them several times and they gave me very unsatisfactory responses. This company does not take their customers seriously. Should I not get my panic button but the end of this month I will be cancelling my service with them and will not pay any cancellation fee. I can’t pay for a service that I am not getting.
