Poor customer service

My Delivery for Contract upgrade on the 12th was unsuccessful because the Delivery address was incorrectly captured, I noticed this from the message I received from the RAM Courrier. On the 13th I called the upgrades customer care and spoke to Dimpho. After expanding and giving her the correct Delivery address I asked if she can confirm the address to make sure that we are o the same page. Her answer was " you just gave me the address " and I asked her if it's hard to just comfirm. Fast forward few minutes later I called again and the the call was answered by Dimakatso who also insisted that address email instructions has sent to RAM by Dimpho. I then required Dimakatso confirm the address with me and the Address was still wrong. Customers are not Idiots when they request things especially after a Delivery failure due to wrong address from the very same people.
