COMPLAINT: Pathetic Service from.Discovery Health Medical Aidl aid

Discovery has messed me around to many times even after calling and calling also have spoken to managers,have requested written confirmation that the correct premiums will be deducted they go again and again into my bank account and take out the incorrect prem I ms leaving my account in a negative which is affecting my credit scoring and not even willing to return bank charges even after giving them proof of the bank charges occurring month in and month out .I really don't think even their Managers in the call center are knowlegeable about their duties or jobs .I would the head of Discovery to investigate my matter and call me back with my funds reversed and banks charges paid back for every month that they have debitted my account for the incorrect amounts. I have constantly have to spend hours trying to get this corrected and still every month the wrong thing is being done.i am.absolutely frustrated and angry with this perthetic service of this company.i also will.like a letter to be sent to the ITC rectifying me credit scoring.
