paid money into someone else's account

I started a seasonal 40 hour contract on the 29th Nov 2015 I was due to be paid every Friday. I havnt been paid once yet because my money had been paid into the wrong account. I was told this past Tuesday that I would be paid today but still nothing. It's festive season and I have no money and had to end my contract earl due to financial strains. I keep trying to call the salaries department to have the issue resolved but the phone keeps getting cut off. Please assist me as this is a serious issue. Thanks
