MY SAFE DEPOSIT BOX EMPTIED OUT BY BANK STAFF

Went to access my safe deposit box at Nedbank Bedfordview on Monday 1 Feb 2016. Found my safe deposit box wide open and ALL CONTENTS REMOVED!!! (substantial amount of cash and jewelry all gone!) As you need both my key and the bank's master key to open the safe they could not explain why the safe was open. No one could say how it was opened and the staff admitted that it has been open for a long time and that they were planning to rent the box out to another customer.They found \another key\" in my file. While testing this key it was found that it could indeed open my safe deposit box without my key. Branch manager Tobie Nogomlana told me that all she could do was to report it for investigation. She did not as much as offer to take my phone number. I inquired (I had to phone twice as she did not respond to my message left earlier) from her on Tuesday 2 Feb 2016 what the case number was. She told me she had the case number and would email me the case number. It is now Wednesday 3 Feb 19h30 and I have heard nothing."
