Call centre agents are not s****ed

Call centre agents are useless. My husband and I upgraded our telkom packages and you guys delivered the first package and then said you couldn't deliver the second one cos the address is invalid. I called and your call centre agent said he would look into and call me back because he can see the first one was delivered and doesn't understand why the driver would do that. He never called back and never looked into it. I called you guys again and was told that I needed to call telkom (in a condescending tone) to change my address cos on his system there's a different address (I have never heard of this address before in my life so I don't know how you guys got it) anyway I then called telkom and then had to call Selldirect to update it but that was the address they already had. After waiting 2 days I then called Courierit again and to my surprise the agent said there's no memo on the account and that she will update the address for me and deliver it the next day . My problem is - Why did I have to call 3 times and call telkom and selldirect and wait 3-4 days if your agents could just update the information on their side??? Are they not all s****ed on how to work your systems and update information?? Never had this kind of problem with fastway/dhl!
