Shocking delivery record

I ordered product from a company in Mooi River, Natal, and as it was dispatched very next day. It arrived in Cape Town the following day 3rd Feb, Thereafter is was sent out 2 days in a row and not delivered. It was sent out again on Monday the 8th Feb and not delivered. The internet tracking record says that the consignee was not available, HOWEVER the person it was being delivered to works from home and always has their cell phone on and I specified in the delivery instructions that the courier was to PHONE before delivering, and no phone call was received on either of the three days it was supposedly sent out. The address is literally 1 minute off the N2 freeway and in one of the closest suburbs to Cape Town central. My parcel has now taken a week and is still not delivered. To make matters worse this is the 2nd time this company has failed to deliver and the time before that my product was sent to Johannesburg instead of Cape Town and sat there for a week before anyone tried to trace the correct address. Even the Post Office during the strike could have done a better job. If Sky Net is so busy why don't they hire more delivery staff, couriers have consumers over a barrel.
