3 Days late delivery_no calls

Worst service experience or rather lack thereof. Upgrade online on the 21/10, received a call from DSV (23/10)that phone will be delivered on the 26/10 before 13H00. Today is the 28/10, 20 calls (on my dime 'cause they never phone) later and still nothing. MTN thinks its acceptable to require a client to call a courier service w.r.t a late delivery... seriously!
