DISCOVERY IS A MONEY MAKING ****

I have been trying to close my account since the 3rd of Jan. I was told I would be sent a settlement letter which then never arrived, so I called again. I was then told it would take 1-2 days to get the letter, and that all I would have to do is pay the settlement amount, and the account would be closed. I got the letter, which said my account would be locked so that no further activity would take place and change the settlement account and that I had until the 9th of Jan to settle. I made payment on the 7th in full, and then this morning I see that Discovery has taken off R466 for fees. Please explain how this is possible since you “locked” my account? And how am I liable for the fees if I have been trying since the 3rd to close the account???
