Awful service

Discovery key care tried debiting me 3 times the amount they should in January which they did not get and then suspended my medical aid. I contacted them ref number *** and they said they will debit the correct amount and requested supporting documents which she sent. They have still not debited me and advised my medical aid will be cancelled by the 1st February if payment is not received. This is awful service from a health care provider I am ill and cant access medication or medical treatment due to this and Discovery does not care even though its an error from there side. Can a senior manager please intervene and assist me as i am not sure what to do anymore.
