Incompetence or just Bad service

I reported unknown transactions on my business account on Saturday 01 September 2018.My account was stopped and declaration forms were sent to me.On monday 03 September,the forms were completed and sent to ABSA.I was told thr investigator will be in touch.No communication from the investigator.I emailed her and tried to reach her on the provided number.I did not receive an acknowledgement of my email.The ***** department told me she is investigating the matter.If a person cannot even communicate with me,how sure am I that matter is being invesigated. It's total incompetence..
