CANCELIATION FOR THE CELLPHONE CONTRACT-SO FED UP WITH THIS COMPANY

I would like to cancel my contract with these people, i received a phone two week ago of which it was a wrong package deal and i made them aware as soon as i received it, that i only received one cellphone instead of two and they told me they are escalating the matter till today I don't have a phone, because i cant activate the one I received because that not the deal I signed up for ....so since they are failing to comply i just wat nothing to do with them ever...I want to cancel and look for the service somewhere else.
