Very slow delivery

Ordered a phone upgrade through MTN Shop on the 10th of October. Received all the SMS's again on the 10th, saying everything was approved and to expect a call from DSV. The first contact from DSV was also on the 10th via sms saying that DSV has received my MTN order. The next contact again via SMS was on the 19th at 19H31 saying that I must phone regarding the MTN order. I phoned the number provided just after 8am on the 20th. I was told somebody from DSV Cape Town would contact me soon. This morning I receive a phone call saying that my order will be delivered on Thursday the 26th between 2 and 5pm. MTN said my order would take between 3 and 10 working days for delivery. So is DSV not failing their client by not delivering on time. At time of writing it has already been 11 working days and I can expect delivery on the 13th working day. This is outrageous in this day and age. I can get a parcel delivered to my Mom in the UK in 21 hours from Cape Town to Seven Oaks, Kent, UK, but it takes so long to get a phone delivered here.
