Discovery heatlth does not know what they doing to their customers

I cancelled my medical aid through discovery. And hda quite abit of savings. They told me that they would check what bank account is on their system., not asking me which bank account I want it to be paid in. I thought that they would have picked up as company who is large enough that am under debt rewiew even with my credit card but still have a savings account with them that they will pay it into my savings account. Yet they decided to pay it into my standard bank account also under debt review and I am not able to access the money to pay off some of my debt. I am told that money that I have paid towards my savings are not eligible that I will get it back but I'd I do I will pay R350 to reverse if they can do that but still not my fault because they did not ask which bank account I want the money to be paid into. Don't think this people know what they are doing. They are just taking and taking, every year they put increases of 10% which was not needed. They need to look after their customers.
