Non Delivery Of Parcel After 2 Months

I placed an order for a pair of white sandals (EU size 39) on Joom on 26 August, with order number 263499LN and tracking number CP920439025PL. The total amount I paid was around 550 Israeli shekels. In the application the order still appears as “shipped”, but I have never received the product. Despite the time that has passed since 26 August, the sandals have not been delivered to me, and there is no clear information about where the package is. I have contacted Joom customer service and I am currently waiting for a reply, but so far I have not received any solution. I request that Joom either ensures the immediate delivery of my sandals or refunds the full amount I paid as soon as possible.
