Started cover today, want to cancel

My cover started today... The rudest phone call from a person working with MiHelp... Terrible to have someone represent your company in such a way... My cover incept today... If we start like this I imagine how would it be if a claim arose? Maybe end of the month sales target pressure, I cannot imagine why the heck you'd allow your employees to speak to a customer like this... You want the sale I get it... I'm not interested, deal with it! But have some professionalism.
