Pathetic insurer and customer service from Palesa.

I am having the worst experience with Pineapple Insurance and a support agent called Palesa. I wanted to cancel my car insurance with Pineapple with cover ending at the end of July. I have explicitly asked Palesa to cancel my policy on the 31st of July. She then canceled my policy with immediate effect without giving me any kind of notice or communication about the terms. I couldn't get into contact with them again on this day, forcing me to start my new insurance (with another insurer) on the same day, to get home safely (This was on 18 July). I am insisting on a refund for the remainder of the month as I have paid for the full month pro rata. I was not informed of any notice period or cool-off period at the time of the cancellation. Palesa confirmed in writing that she has made a mistake and that the system had an error, allowing her to wrongfully cancel with immediate effect. Palesa is now refusing to give me her manager's contact details for the matter to be resolved. Because of Palesa's incompetence and negligence, I am now paying a double insurance premium for the month. Palesa made a mistake. I do not want to be covered till the end of the month, I want my money back.
