Failed delivery

I had a delivery scheduled for Monday from DSV. The driver arrived, but he couldn't leave the parcel due to a technical glitch with their delivery app. Since then, I've been waiting to be contacted. They finally reached out to me today, on Friday, four days later, to schedule another delivery date that’s at their convenience. I've been waiting all this time for them to contact me, knowing that my delivery failed. This item I purchased has been paid for and is billed monthly. I should be using it by now, but DSV failed to make proper delivery arrangements, and all this inconvenience has to come out of my pocket. MTN should change their couriers and find reliable ones; they might lose business due to the unprofessionalism of DSV.
