This is the second week that I was waiting for a parcel from DSV Bloemfontein, that had been in their warehouse for three business days, but somehow they don't send it out for delivery. I tried to phone them every time this happened....no answer! I hold on to music playing for about 20 minutes. Eventually I collect the parcels myself. And no one can answer me at their warehouse or on the national call centre line as to why the parcels just stay in their warehouse without delivery, they just say they don't know. There is a serious issue with their service. Unfortunately one of my suppliers use them to deliver parcels, but I would never use them myself. I have had the same issues with them in the past every time somebody use them to deliver to me, it's an endless wait and you can't get hold of anybody. They are probably the slowest courier in the world, I'm not exaggerating.
