THIS IS SERIOUSLY BECOMING A JOKE

I received a sms from FNB indicating that my account is in arrears?? Excuse me as far as I know my account is up to date and paid for. So I phone you credit card division to be told that my debt order has been suspended, WHAT THE HELL. Please explain to me when I was notified of this because now my account has been handed over because FNB has not received the payments for Feb and March ***, I now need to pay R3630 because of your incompetence.. This is against consumer law and I will be getting my Lawyers involved as this is pathetic practise.. After 6 months of trying to get my retrenchment policy paid out and now this s...it##... WHY WAS I NOT NOTIFIED THAT MY DEBT ORDER HAS BEEN SUSPENDED... you guys got your money that was owed to you now what is it you want from me this is ridicules. I am tired of this as I have sorted out all my debt orders and they are up to date now you send me a msg that I am in arrears!!! *** I am in shock.. Im sick and tired of this and im going public with this on social media... I want proof that I was notified of my suspended account as this is bad practise.. Really
