Medlife — Spam messages from Medlife even after they deleted my account 6 months ago

I placed one order on Medlife in September 2020, ONE ORDER, and I started receiving spam messages on daily basis. I was in touch with their team constantly from September 2020 to December 2020, and finally after 4 months, their team was able to unsubscribe me and they said they have deleted my details.

Today, I received another spam message. In between these 6 months, I have not contacted them a single time, haven't placed any order on their website, and haven't even opened their website. And somehow after 6 months, my number has magically reappeared in their promotional database.
