Service is non existent

Purchased items from Temu that utilizes Buffalo ex as the couriers for the parcel. I paid the delivery fees. Nobody phones me to arrange delivery but they phone me on Saturday at 12pm to say they are delivering. I am not at home and the delivery person makes a 20 second call which I do not respond to. I have now tried to get them to deliver but the phone plays "the sounds of silence music while you wait but no answer after 3 or 4 minutes. I have tried a couple of times with no answer. I have also tried leaving a message on their Whatsapp number and no response from that either. They told me they got to response from my cell number and sent me a URL to organize another date for delivery but all it asks is to confirm delivery address but no date section. This is terrible service. I will never deal with them and Temu again.
