I cancelled the policy i had with Dotsure on the 13the of July 2023 WITH IMMEDIATE EFFECT because i had found a better insurance for all my assets. When i called for cancellation, the lady i spoke to promised that they were not going to debit my account. To my shock and surprise, they debited R1385.22 I called them on the 15 July for my refund. I am so shocked because they only refunded R819.75, which means i was debited by two insurance companies. I need the balance of the money which is R565.47 to be paid back to my account as i have cancelled with them
