No feedback or contact after leaving details

I visited the Greenstone branch on Saturday (04 May 2019) in order to inquire as to what the settlement value of my home loan is as I require this information urgently. I was advised that I would need to contact their call centre as they could not assist in the branch. They allowed me to use the telephones located in their branch. I was advised by the person at the Call Centre that a specialist would need to assist me as they have to perform the required calculations. As it was a busy day, I was asked if I could leave my contact details so that the specialist can contact me. I was advised that I would either be contacted later that Saturday or on Monday (06 May 2019) . As of today (09 May 2019)I have not received a call from them or any feedback with regards to this matter I urgently require this information. Can somebody please assist me.
