POOR DELIVERY SERVICE

On 17th April I get a sms to notify me of delivery. I noticed that the delivery address is wrong and tried to contact RAM Couriers only to be informed of their office hours from 07h00 to 17h00 Monday to Friday, I phoned 16h58 and no answer. Today 20th April I have been trying since 07h00 to get hold of them to inform them of the correct address. The Courier guy phones me at 09h37 to say that he is at my gate, NOT THERE! I told him that the address is wrong and gave him the correct address which he recorded and confirmed via telecon. RAM Courier phones me for the correct address and confirm verbally the address for a second time. At 16h55 I track my delivery only to note that at 16h52 delivery was unsuccessful. How is it possible that none of the two gentlemen I spoke to could not give the correct address through. Is it that difficult. I understand that we are working under abnormal circumstances, but surely how difficult is it to get the delivery address sorted out?? Come on guys, RAM used to be a top courier to rely on, what is happening. When will I get my parcel?
