Unhappy client

So I ordered from Temu on the 2nd of March which I normally expect my order to be delivered in 2 weeks so some of the items were out of stock which I got a notification of that and understood I would wait a bit longer than expected, my order was then shipped and arrived at Buffalo warehouse on the 26th according to the tracking information provided, I patiently waited and expected it would get delivered within 3 to 4 days since it's now in the country until I realized it's no longer moving it's stuck in one place , on the 29th it then moved to ' customs is checking documents ' step and it's now stuck there , yesterday the 31st I decided to follow up with them via there help center , I emailed they ignored , whatsapp they ignored told me their live agents are busy nd they will get back to me. Today it's the 1st of April I haven't received an order I placed on the 2nd of last month , what a frustrating experience
