No Response from Forensic Department

My bank account has a hold on it, its been a month and a half. I went in to the branch and was advised that FNB forensic is investigating the money that was transferred to my account. After following that up, the owner of the FNB account who paid me with her FNB account told me that, FNB wanted proof of payment that was in her account. And on the 12 Aug, a lady called Lisa from FNB forensic, advised that they have proof of payment and will remove the hold on my account. Till day, no phone call nothing. My life is on hold by FNB Forensic depart, matter is handled by Lisa..
