INCORRECT MONTHLY CONTRIBUTION DEDUCTED TWICE!!!

In June they deducted R168 more than they should have I then enquired with \Brad customer service"online and was told to email my payslip to [Email Removed] \""so that it can be rectified asap and the extra money can be paid back into my bank account\"" upon doing so I received an automated out of office reply stating that she was on leave until Friday 3rd July I then sent another email on Monday 6th with regards to my previous email but got no reply. when I asked \""Brad\"" why the extra money was deducted I was told that most companies give increases this time of year so they just assumed I got an increase! I then spoke to \""Brad\"" again telling him that Belinda has not rep**** and was told to email my payslip to [Email Removed] on the 10th and received a reply on the 12th saying they have received my latest payslip and i will receive feedback shortly. on the 29th I still had not received any feedback and emailed AGAIN to find out whats going on. I then got a reply the 30th saying they have review your latest salary advise and my contributions has been adjusted accordingly then on Saturday the 1st they deducted R168 more AGAIN! and i haven't received last months money"""
