Rimborso mancato

Hi, i need a refund for two orders, GSO13Q22W002CD0 and GSO130228005AVR. Two orders, returned with Inpost locker and succesfully delivered ( i have delivery proof) and absolutely no refund for both! It’s over a month and i’m tired of waiting, refund me now or i will sue you! I am a gold shein customer and i don’t want to lose 30 euro of refund for each order ( 60 euro in total!) , hurry up and refund me! There are no reasons for that
