Wesbank Fleetcard

When our business apply for Wesbank Fleetcards they asked us to make an investment and sign a session to Wesbank Fleet. In September 2019 we closed the account because we was not happy with the service. We contacted Wesbank Fleet and complete the necessary forms and also attached the fleetcards that was cut to proof that we have destroyed the cards. We asked when can we get a letter that states that the session was cancelled. They informed us that we need to wait 3 months to make sure there is no outstanding transactions on the account. Now 5 months later and despite numerous emails we can not get Wesbank Fleet to give us a letter so say that the session is cancelled. Now after 5 months we are back to square one because they emailed us a form to complete to close the account.
