faulty statements

According to African bank I am in arrears with one of my accounts due to payment reversals. However according to my bank statements no reversals occurred. I got retrenched and insurance paid account for that period untill debit order was presented and went through.<br> <br> I phone explained and was put on hold for 30 minutes until I was cut off. No assistance. Then phoned head office but cannot put e through to a senior person for assistance.
