Poor service (***** department)

I am tired of calling ***** department everyday using my airtime and worse part is that funny annoying music that is playing background,I have a serious problem,last year November I was ****med a lot of money and all my money is gone because the was no money on beneficiaries account but my problem is they didn't go deeper in doing investigation because they were suppose to explain what really happened,was the money transferred or it was withdrawn and when I try to ask this questions their telling me that I must talk to the police
