Appalling customer service

I placed an online order on 10 Feb with a turnaround time of 3 weeks. Today is the 9 April and I'm still waiting for my delivery. Their timelines changes whenever you call. I tried escalating with their management, but they will never put your call through, either the hang up on you or transfer to another customer support. Their service is appalling. I regret placing my order with them. Please refund me if you can't deliver on a service. Extremely disappointed.
