Bad service cancellation of cover

To whom it may concern. Membership number: *** I am writing to you for urgent assistance. I have dealt with discovery last week due to to a debit order on my account. I contacted the staff and they informed me the debit order was successful and everything was fine. A few days later I got an email stating that my cover was suspended and if I do not pay within 14 days it will result in cancellation. When I contacted discovery prior to the email received I asked the agent to make arrangements for a different date for the debit order to go of which they said they were unable to assist. I therefore went out and took out cover from another medical aid company. I have been trying to get hold of someone and every time i am put on hold for over 10 minutes and now I am being told I must give 30 days notice. Please ensure that my medical aid is cancelled immediately and no funds deducted from my account due to the above and lack of service.
