POOR DELIVERY SERVICE...!!!!

I ordered on the 20 February 2021 and my delivery scheduled for the 02 March 2021 before 15:00 , when i checked my order after 3pm on 02 March 2021 it said" recipient unavailable to collect order"...and it rescheduled for 03 March 2021 before 15:00 , i checked again and it says "recipient unavailable to collect order"...this makes no sense as i work from home and never received a call or missed a call in both days...!!!!
