Continued suspension of membership.

I have NEVER before in all my years experienced such poor service from Discovery. I am unemployed and make a manual payment to Discovery before the due date. Immediately I send an email with the deposit slip and my member number as the reference. WITHOUT FAIL they suspend me for late payment! EVERY SINGLE MONTH! If I have extra money I will pay it even if it is R100. I am currently in advance...guess what...I'm suspended again. My membership is only active for about 4 or 5 days a month! They are playing Russian Roulette with my life as I am a cancer survivor and need to take chronic meds! What if something should happen to me and I'm rushed to emergency only to find I'm suspended....I will die! Needless to say I am going to their headoffice on Monday and heaven help me to keep calm.
