Bad service from Uber eats

Good day

On Sunday 03/01/2020 I have placed a order on Uber eats to avoid going out due to the second wave happening currently in our company. I wanted to purchase all my monthly shopping on Uber eats which I done. But when my order arrived I was disappointed and disgusted by the service I get from Uber eats my order was totally wrong and I received half of my goods I order some of my good were damage as well . I've requested for a refund on the goods I haven't received and still today I haven't received my refund back they are still investigating after I've sent them all my details and I have paid them in full. The customer service is very bad at Uber eats I will never use this app again I would just like them to refund my money they owe me because I need to do my monthly shopping
