No Feedback on Lost and Found Items

On the 21/11/2017 I left an important white Envelope at the B Terminal at the Midrand station, as I was about to board a train heading to Sandton... I called the call centre to log a case on the lost and found Items. I spoke to an agent called Nikil. He said he would log an email to the right department...but till now no response. He stated that I will receive a comfirmation email in 2 hrs but no email as yet. I called the lost nd found number which was given to me and the phone just rings endlessly. This is unproffessional. I really need the envelope. It has important documents
