Poor Service!!!

My parcel from Shein arrived a few days ago. I received the sms from Buffalo Logistics advising that my parcel will be delivered in 24 to 48 hours. 48 hours has passed and still no delivery. I called them this morning and was told that it would be delivered today and got nothing. On the app it shows delivery not successful due to address and when I called the call centre this morning, I was told that it's not the address but the driver could not deliver yesterday due to the volumes of delivery. There has been no update. This is just pathetic!!!
