Retrenchment claim a serious headache

I have been sending the necessary documents in order for my repayments to be frozen on my vehicle due to retrenchment since 11 Aug. After emails, written notifications and phone calls between myself and Masentle Sekano and my previous employer confirming that Nedbank had been in contact with them to confirm my retrenchment date, my repayments have not been frozen up to date and my cheque account is now in overdraft. I've emailed written instructions twice to indicate which months the payments had to be frozen and still nothing has been processed for these repayments to be frozen for 2 months.
