Poor TAT

I received the worst service from DSV, I had made an arrangement with DSV to have my MTN parcel on Friday between 08:00-10:00 am. I made the arrangement to have my parcel delivered at home at this stipulated time as I know that where I work, i struggle with network on my primary no. (I did provide my alternative no. to DSV, which does not have network issues) and did not want to complicate the delivery process. I made arrangements at work to commence my shift at 11h00am, as I had a parcel that was going to be delivered between the hours of 08h00-10h00. At 09h22, I made my first call to DSV to confirm the time and was informed that my parcel will arrive by 10h00am. I did not get a call or delivery, I made a call again to DSV at 10:07 and they informed me they did not have the couriers no. and they would send a query to the team in South Africa and they would contact me. I waited and did not get any response. I called again and asked for the contact no. of the delivery team in Cape Town and they supp**** me with the no. I called the Cape Town office and they tried to make contact with the courier, whom was on voicemail. The lady promised to provide me with feedback as soon as they got ahold of the courier. I made multiple attempts to contact their no. again and they did not answer. I am quite unhappy with DSV's service.
