Empty Promises

At the end of June, my salary looked a bit light. They deducted twice on one policy. I then consulted my HE and Unions and I was told, it was a glitch in the system that affected everyone. But to be rectified, I had to go to an old mutual branch and their call centre in Cape Town. The amounts will be reversed within 7 days. After few attempts, it's was reversed and some of my debit order had bounced. I then instructed old mutual to stop deducting from payslip, but from bank account. End of July, they still double deducted from my payslip and samwu which is not my union. I went in to complain and cancel the policy. I was told I can't, only a portion of it. That month, I also had debit orders being returned and my money was reversed towards the end of the month of July. End of August, the same thing has happened again, I am not sure where to run to now. My salary is deducted anyhow and reversed anytime and without an apology nor penalty of my other bank charges for returned debit orders. I'm short again this month. Some debit orders will bounce and my record is *****ed and old mutual is not bothered.
