Old Mutual brokers

For so many years I've had my funeral policy with Old Mutual, until last year October i decided through the assistance of the broker to switch my policy to a comprehensive + family funeral plan for better benefits, however, i recently discovered that instead of changing the existing policy plan he opened another one, where I'm the only one covered, only policy owner is covered and my entire family is excluded, at a very ridiculous amount i must ssy. This has caused a huge financial gap as I'm now paying for 2 policies, which is something i didn't ask for. I now want to cancel the newly activated policy and demand my refund from October 2023 to date
