Updating Details for marketing

Dear FNB,

Today again I was contacted by a *** number that says Matrix to update my details. The person told me I need to update my details. He knew my email address. I immediately told him straight that my details are update on my banking app and that everything is up to date. Please could you stop sharing my personal information to marketing companies? I'm not interested in buying anything. If I need something I will contact someone if need be.

Regards, FdP
