Cannot cancel Discovery card keep taking fees

I have been trying to close my Discovery card since November 2015, as I was emigrating. I paid the account up in full and called Discovery to close the card, at that point I was told an agent would contact me to finalize the process after 5 working days. I called Discovery after 10 days to be told the area dealing with this were in a backlog. So I again requested this be done and was told the problem would be escalated to a two day turnaround. Yet again this did not happen. On calling the third time I was told that as I was emigrating I had to complete a form, even though each time I Called to cancel the card, I did state that it was due to the act I was emigrating. The form didn't arrive. So 24 hours later, I called again only to discover the agent had sent the form to the incorrect email address, even though the correct one is in their system. I completed the forms returned it on or about 11th or 12 th December. The card was still not cancelled ! Even after finally getting hold of a manager who stated they had not informed the life area timeously (protecting a zero balance). Guess what I am now overseas and after following up again, credit life want another form & 30 days !!
