Still waiting for my salary

Foschini replyed saying their regional manager will contact me and he or she never did I want to knoew when will I get my salary! How long must I wait or maybe they dont want to pay me? I spend 80rand of airtime I was holding on for Michelle up until the phone is on voice mail even the ladies at switched board I clearly hear they are tired of me phoning! I dont know whats so difficult in paying my money that I worked for.
