Rotten service

In October 2021 I placed an order with Shein Online Store. I paid my taxes on 29 October 2021 and they informed me that my package will be delivered by Buffalo before 11 November 2021. I followed up by 27 November and they said due to Xmas orders it will be delayed. I contacted them on the 7th and 15th December 2021 without any success. At beginning of January 2022 I followed up again and they informed me that my package is destroyed in their warehouse because it was their more than 3 months. What bull****s so conveniently. Shein must really change their courier services because Buffalo's service is pathetic. I lost R1440.00. I need advice how to recover my money
