UPS Courier bas service

Very ppor service from UPS South Africa , I have waited for order to be delivered 1st never got a delivery notification I had to track my parcel only to see that its out for delivery must wait 8am-6pm. Now i cant stay home whole day waiting for something I dont know. I tried to call the call centre to try and atleast track the driver and they told me he is not picking the call, I will be called back now its 14:30 parcel has not arrived not even a single notification ..trying to call their call centre have been in queue almost 30minutes now. I dont know why Amazon uses UPS its not the first time I have this problem. You guys must learn from Fedex or Courier Guy on how things are done
