Steer clear of Discovery Bank, no customer service

I have been trying to close my discovery credit card account since the 20th of July, i have called in 4 times now around this. I even received an apology mail from their group chief executive on the 4th of September around their unacceptable service (no doubt a system generated mail, as i have responded twice with no response). Discovery have told me that they had a technical error which occurred on the 11th of September which prevented the payment, this technical error has almost lasted 2 months, so I'm calling BS and delay tactics. I was told on my last call to discovery that their account closure SLA is 30 days, how is this enforced as I am currently on day 107. Be very careful with this lot, I would recommend using VBS over discovery right now. Terrible service, steer clear of this bank. They are quick to sign you up and promise the world but you can never leave.
