DSV is pathetic. no customer service

I recently upgraded my MTN contract, DSV called me to arrange delivery for today between 9-12. I asked them if my phone can be delivered in the afternoon because of work, they said its not possible, I had to sign leave today to wait for the phone which never arrived. nobody at DSV office in durban answers the phone. pathetic service. I understand we have had some flooding in KZN but atleast notify customers that there will be no deliveries. Joburg branch keeps saying my parcel is out for delivery. Tracking no. provided doesnt even work.
