NO COVER!!!

Just got the shock of my life calling Discovery's call centre. My debit order did not go off at the beginning of the month as per normal for my membership (funds were available). I gave the call centre a call today and asked the lady what the issue is with my debit order. She looked into the problem and informed that my membership had been withdrawn. Apparently Discovery's brokers gave them the order to withdraw my membership, because I'm unemployed...all this while I'm at work! What a joke, I didn't know I'm not covered and I had no idea that don't have a job anymore. If I didn't call them today and had a accident, I would have had NO COVER in place. Been with Discovery for a long time, but this is absolutely shocking and unacceptable! ??
