Temu - Buffalo deliveries - BAD CLIENT SERVICE!

I ordered from Temu, Buffalo is the service provider for my delivery. Firstly they apparently attempted delivery to my office on a public holiday, which is strange because #1, its a office and #2, they usually always call before delivery. There were people on the premises and building at the time and there are lockers outside the building where parcels can be delivered so it tells me no one even bothered to deliver then secondly I was told parcel was out for delivery today, no one can assist with a time or even the drivers contact number. When I call the call center I keep ending up at the incorrect department even though I choose the correct numbers for international deliveries. So now I am sitting here with no package and no way to find out when it is being delivered and the people I keep getting through to are extremely unprofessional and rude and tell me they are not allowed to direct my call even though I press the correct numbers #1 and #1 as stated. The client service for buffalo is beyond ridiculous!
