Skynet couriers useless

Ordered a package, on tracking it shows it was received by them and out for delivery. 30 November at approximately 9:30, shows could not deliver as consignee not available. Utter nonsens we are 3 people at home as I work from home, and the students in our household is done with exams. Later that afternoon tracking shows Bad address?? Every day same thing it is out for delivery, try contacting them telephonically and they just keep you waiting.... Why can other couriers deliver on time and also at the correct adres, no such nonsens as a bad address. Will never be able to recommend them
