Dsv couriers

Absa uses them for delivery of bank cards. I was phoned twice last week by them to confirm delivery of my card on Friday. I had to cancel appointments to wait at home for the card. The driver never phoned (like they promised he would) neither did he show up. I tried to phone them on Saturday morning (their website says they are open on Saturdays) only to get a message that they are closed. Phoned today (monday). Phone just rings. On second attempt somebody answered. I explained the situation and she said that she will get hold of the driver and phone me back. More than an hour passed. I phoned again. Again the phone just rings. Tried again. Somebody different answers. Explain again. She hands the phone to the person I spoke to the first time. I explain again. Then get some (for me unbelievable) story hat the vehicle that was supposed to do the delivery was in an accident on Friday and they apparently only found out about it this morning. Now if this vehicle was really in an accident, surely they would have known about it then already. These vehicles have trackers. Even if the people I spoke to only found out this morning, then they should have been able to tell me that the first time I phoned. So I don't believe them. And then they say that the earliest they will now be able to deliver is tomorrow. That is no guarantee that they will deliver tomorrow. I just feel that their customer service is appalling. It would have just taken a phone call or even just a message to explain if they were encountering problems and then they should have dispatched another vehicle to do the deliveries. Searching on the web, I see that they actually get quite a few bad reviews. Maybe the banks should reconsider using them and find a company that will provide better service
