Frustrated by pineapple insurance

I took a cover with pineapple last year around July 2024. The cover was under someone else's name then December I decided to change it to my name, pineapple would promptly respond to my whatsapp messages and email. For some reason the premium didn't go off after changing it to my name. I tried contacting them to make payment arrangements, it's like they went awol. Now, because my car didn't have a cover and pineapple wasn't responding I decided to get a cover else where. On the 10th of January I sent a what's up telling them that I want to cancel my cover with they, they called immediately to understand how they can assist me but I told them my decision is final and they promised to cancel and send me a confirmation.

To date they haven't canceled, they do not respond to my whatsapp messages or emails and the most frustrating thing is I can't even call them. I can't change my account because pineapple insurance, I just need to get them to cancel, I don't know how. I think they are ****mers and this has to stop
