Very poor customer service

I have been the main member on Polmed medical aid since 1996, after my husband past away. 22 years down the line, it's just problems. I would like to know if the people working there, are educated or is their systems so outdated or maybe over loaded.

They are the worst to reply on an email that was sent to them, you only get the automated response and that's it.

My membership was terminated some 3 months ago but definitely not the debit order, and I'm sure nobody checks it, because I've had the payment stopped and reversed by the bank but they continue to deduct. And every time it cost me money.

I tried logging on to the website but my membership number doesn't figure on their system. What am I to do?????
