empty promises by iwize

This people are ****** I once wanted to cancel my insurance with them as i had received an sms stating that my basic excess is now R4000 from R500 and they reassured me that my excess basic excess has not changed and that there is no additional excess to pay. now I have submitted a claim they are telling me about additional excess and state that their assessor say my tv and decoder have been damaged by lightning, while my iterms where damaged by power surge. they then send you from pillar to post.
