NO FEEDBACK REGARDING REFUND

I've made an online order on 04 April 2023. On 14 April I've followed up because my tracking status was still order received and delivery date was 10 April. After MANY follow ups no one could confirm where my order was because it was a third party supplier. So I've requested a cancellation and refund. Every time I call they just say it has been escalated. Up until today I have not received one phone call or email or sms and still NO REFUND!!
