Policy cancellation please

Very bad experience shame i want to cancel my policy with you guys i have been trying to get ahold of you and for some reason i just coulnt i Tried using your so called whatsapp and customer care line it ddnt work. I joined your policy on a certain lower amount premium through your agent Cathy last year in makhado louis and then i met your agent i forgot his name this year in burgersfort told him i lost my sim card and he said he will give me another one only for him to increase my premiums i dont know why please dont ask and guess what? He ddnt even give me the sim card because i refused to do debicheck but somehow it was too late coz the premiums changed and im not happy at all. I sent the email with the same contents i hope i get help because i dont know what im paying for now that you changed my policy..But i want out please cancel it im fine with it. Thank you
