No delivery. Terrible customer care.

I missed my delivery. I tried scheduling and still nothing has been delivered. I have been tracking and no update on fedex website. The customer service all they say “we’ve prioritised your shipping” after making you wait for 30 minutes on WhatsApp chat. I am even scared to ask for refund seeing that no one gets their money back. I have been online shopping for about a decade now. I never experienced anything as terrible as this. Highly disappointed.
