No feedback from Absa on 500k ***** investigation

I have been subject to ***** of 500k on a purchase of a home. After contacting Absa on the 9th of January and submitting my enquiry to the ***** Department I have not had a single response. Subsequently I have visited my nearest branch on four or five occasions and called the ***** line yet No one can tell me if my case is been looked at yet alone received. Shocking service to a loyal customer. It's my kids future at stake here,entire life savings. The longer they take the more difficult to track down these *********.
