I paid for more storage but my iPhone storage is the same

Good afternoon, I pay a monthly fee of 3490tenge for increased storage, but the actual storage on my phone has not been increased. Please expand my everything, as photos and videos are archived and cannot be opened! why then do i pay monthly storage increase? when im going to the email where apple says that my storage increased and then go to main settings it became increased, but when im going to the photos and videos, its written that my storage are full, therefore all photos and videos can not be opened. please reply me! please increase me my storage as i paid for 2 months but in fact apple didnt increased my storage
