Waiting a month for an online order

I placed an order online exactly a month ago and have still not received it. Took me 3 weeks to get a hold of someone, only for them to say sorry for the delay, your package should be on it's way in 3 - 5 days. After that nothing again. This has been the most useless customer service I've ever experienced. No wonder Edgars is going under. I understand the lockdown has made trading difficult, but the lack of communication is what is driving me nuts.
