Incompetence!

This is the umpteenth time unauthorized payments have gone off my account, and it KEEPS HAPPENING. I received an sms of a scheduled debit order of an arrear amount I had paid 2 weeks before. I called the Call Centre to make sure it doesn’t go off as my account is up to date. She confirmed this and assured me it will not go off, IT DID! Now I have to go into the bank to to reverse this debit! How. Are. You. CONTINUOUSLY. This. Useless. This is seriously going to make me move to Planet Fitness! So irritated!
