Unable to provide settlement letter

Going to two months now and this company is unable to provide me with a settlement letter for my edcon account. The lady Michelle is totally useless, reads emails and chooses to ignore. Not a single call I've had from these people. The receptionist transfers me to someone who says its a process. They are all unable to call edcon to close this account and to confirm payment in full was made 2 months ago. Totally ****ed off.
