Bad service and ************.

I cancelled my medical aid on the 31st of May 2021. Once after that inwas told that I owe the medical aid R1500 because I had used my savings. Premiums from January to May exeeded R15000 and my savings per annum are R7000. When Discovery called me I advised them that I was never told that should I cancel I will be liable to pay that amount. I further asked for the recording where I was told of this information and they can't assist with that. Now they are promising to blacklist me for something that was not told to me. I will write on every social media page until I receive help from someone
