iWyze insurance

Hi my name is Thandiwe and i have a complaint about iWyze insurance. Recently i took up a car insurance policy with the company and i now want to cancel it as i no longer using the car. When i took up the policy the sales consultant told me that should i want to cancel the policy within 15 days i will get the full refund. Now i called them last week to cancel the policy with them and they told me that i can't the full refund as they need to get their money for the days they covered my vehicle. Furthermore, they told me that they can't cancel my policy until they investigate the matter and listened to the recordings and they are not sure when will that be and automatically they debit on the next date even though i no longer in possession of the car. I am not happy with their service and i would like to get my full refund.
