Standard bank. Zero Standard bank

Today 12 /2 there i received 2 x messages someone had logged into my account It was nor me. I calked the ***** line. Once I got through a lady started looking into the query and kept me holding on for 26 minutes. I had to listen to music over and over. Eventually they just cut me off. I tried calling the ***** line again. After listening to their recording press1, press 1 etc. I finally get through to *****. Again kept holding. But after holding for a long time AGAIN hot cut off. What the hell!! I keep promising myself to move both my business, private and family trust accounts to another bank. Well now will definitely get down to doing it. That is if someone hasn't depleted all my accounts?
