Terrible service and confusing instructions

Booking reference CZBJE5

I forgot my ID at OR Tambo at the check in counter. When I boarded , I notified them of my ID and they confirmed that it was there. One of their employees was given my ID to take to the boarding gate and never arrived. I was then instructed to board the flight and collect my ID upon my return. On my return, I waited for two hours going back and forth to lost and found and the service desk only to be given an email to which I must send a request for my ID to. I have send the email only to be told to call the service center. I have called the service center only to be told the matter will be escalated and I will hear from them soon. It has been two weeks now and I still do not have my ID. I almost was not allowed to check in when I was returning as I was given the wrong information that I would be allowed to check in without my ID on my return. The service is so bad, this is not acceptable.
