They keep debiting the wrong account! Their communication also sucks

I changed account details. I informed them via email then they asked me to changed the details on the app. I did so immediately and saw that my new banking details are reflecting.

However Pineapple Insurance kept debiting my old account! I raised this issue. Tshepo from Pineapple then tells me that he will speak to the tech team about it but does not give me an outcome. A few weeks later I get an email telling me that my policy has been cancelled due to non-payment. I'm left confused because when I open my app, my new banking details are reflecting but they are not debiting the correct account.

What makes this even more frustrating is that you can only get hold of Pineapple insurance via email or their online chats with a robot. I'm unable to find contact details to sort this out immediately.
