iCloud notification to upgrade or manage my storage doesn't stop

I get near constant (like every other minute it sometimes) notifications from iCloud that my storage is almost full and that I should either manage or buy more storage. Initially it was about 4.95Gb out of the available 5Gb but after literally being pestered for weeks I upgraded my storage to 50Gb so it would stop giving me notifications but IT STILL GIVES ME NOTIFICATIONS. This is despite the fact that only 4Gb out of 50Gb were being used and I even deleted my iPhone backups so now its closer to 2Gb and I'm STILL GETTING THEM. This is incredibly annoying and distracting and the complete lack of a solution is incredibly frustrating. If anyone has been facing the same problem or knows a solution please let me know because I've already tried two, deleting things stored on iCloud AND buying A LOT more storage.
