Discovery Insurance

So I am currently insured with outsurance, and through a friend I heard about discovery insurance. Everything sounded good while they complimented the terrific services they received. So my friend gave me their broker's ( Igshaan Ismail) contact information and I phoned him the following day to get a quote for insurance. 2 days later I received a quote and decided to sign with discovery insurance. So I contacted Igshaan Ismail and informed him that I want to sign and how do we go about in canceling with outsurance, to which he rep**** that he will handle it all and that I don't have to worry. The reason is I wanted all my policies and medical aid under one umbrella. So after I signed he contacted me and said that I need to contact outsurance and cancel myself. Ok so I phoned outsurance and my broker at outsurance re evaluated my policy and gave re generated a quote. New contribution that was given to me was better that discovery to which I could not say no. And everything stays the same. So I then contacted Igshaan again and explained that I can not say no to this offer and he asked me what the new premium is, so I told him and he said "yes discovery will not be able to beat that", and he also suggested that I stay with outsurance and that he understands. So i asked him to please cancel the insurance policy and he informed me that I just need to email him with the policy number and that I want to cancel. I did this immediately and asked on the mail to please confirm that he received the mail and that it is canceled. This was done on the 17th of December 2021. I have sent numerous emails to him and whatsapp's that is ignored. I have sent all correspondence to *** and all I get is an automated email to say you have received the mail. We are going on to 3 weeks now with no outcome or confirmation. A debit order went off this morning which I already reversed. Hello peter is my first step, ombudsman also will be contacted as this is really unprofessional. I have a medical aid and life policy and I am so happy and satisfied. But insurance side? I am very happy that I decided to stay with outsurance, if it takes 3 weeks to get correspondence what would have happened if i decided to stay with the insurance and really needed them?
