refund of debit cancelled policy

I joined the Pineapple insurance on 23/11/2022 after still being covered with my previous insurance i told them to start the cover in December.

I requested a refund of the premium on the 25.11.2022. I had a bad reception with this insurance to a point that I received the refund after weeks 09.12.2022

I told them to cancel the insurance I am not happy with everything. 1 their numbers were not working, sending emails no replies, sending whatsapp nothing, sending messages on the app still nothing.

I wrote on hello Peter then i received a call from them. TODAY 28.12.2022 they debited my account after telling them to cancel the insurance and I am being told about 30 days notice yet in the weeks whereby i wanted assistance they were not reachable.

i need justice this is a **** **** ****

I cannot be covered with 2 insurances
