Wesbank Car Finance

My car was on payment relief for 3 Months then i asked for an extention as i was not back at work i only started working on Level 2 for 3 days a week. I never heard anything back after they sent me an email saying it is in discussion and they never debited my account so i assumed the extension was approved. Its December they still haven't debited my account but i received an sms and an email saying im in a arrears. I've been trying to call them and no one can assist me so a lady told me she will find out and call me back and still no one called, ive called again and then they the guy said i must hold the line and then the call drops. Someone also gave me another number of the person that was "working with my account" and the number is no longer in service. This pathetic that no one is able to assist but quick to send me an email to say my account is in arrears and that they never even Debited my account accordingly.
