Não fui ressarcido do valor pago a mais na compra

Fiz uma compra online no Carrefour no dia 23/12/23 e recebi em casa a compra com vários itens faltantes. A empresa não fez o estorno na fatura do meu cartão do valor pago a mais pela compra. Já entrei em contato com a empresa no dia 12/01/24 e no dia 05/03/24, porém até hoje a empresa não fez o estorno no meu cartão.
