Never received my full salary for work done

I worked for Pilates Unlimited as a instructor for more than 3 month's. I resigned and worked my full last month as Tanya and I discussed will be appropriate. <br> Now she doesn't want to pay my full salary because of clients accounts in arrears. She never said it is my job to contact them about theirs accounts. <br> She just simply take it from my salary for thEm. I went and Co Contacted them for the money, now she still refuse to pay me now that I went though trouble to Contact them because it's not my job? But if it's not my job why won't I get paid for the work I did do and had to do? She never said refuse a client because his account is in arrears? I don't think it's legal what Tanya is doing and I always gave my best. <br> I know it's hard to lose a employee but to take their money for someone else's work not done is not right at all. And she is blaming clients now that they don't want to pay but they tell me otherwise. <br> I really don't believe this is how a business works after all I worked every morning from 5.30 even earlier for certain clients and ended after 7pm at night. I really just want to receive the money I deserve for the hours worked on my statement for March 2015!
