Buffalo Couriers make shopping with Temu too hard

I've been waiting for a parcel from Temu and a Buffalo driver tried to deliver it on Friday, while nobody was home. I spoke to the driver on the phone and he said he'd phone me on Monday morning. As today (Monday) was the only day I could guarantee I'd be home, I waited home all day, but didn't hear from him. In the meanwhile I wasted hours trying to contract their telephone or online support, but all I got was BOTS that told me my parcel would be delivered within the next 24-48 hours. Eventually I phoned the driver who said my parcel had been returned to the warehouse and he'd phone me when he gets it back. As my schedule for the next few days is pretty busy with appointments that can't be changed, how can I be sure I'll ever receive it?

I'll be reluctant to order from Temu again.
