C Surance

hi there<br> <br> i was surprised to have seen an increased premium go off my account for c surance last month. i subsequently called the call centre to which i asked for an explanation to which i was advised an email was sent out advising me of this. to date i have not received this mail, i also asked for my policy schedule to be sent. i called on about 3 occasions and was told i would receive this in 2 weeks. it's been more than 2 weeks and i have not received the email concerning premium increase or my policy schedule. the call centre number now has an error tone. please advise a way forward asap. also the increased premium has now gone off again this month without my consent.
