No impressed at all

I used discovery banking for a trail period but found that it was not to my liking. So a few weeks ago I informed them that they can close the account. I had no other communication until yesterday when a very nice lady phoned me and on a 45min call tried to convince me that it is for me. Eventually, I agree to use the service but at a reduced level with a reduced cost. So what happens? They took this opportunity to quickly throw in the higher monthly banking cost before the did anything. And their so-called 24/7 phone us any time does not work and there is no, absolutely NO other way of contacting them. So Discovery if you are reading this, CLOSE THE ACCOUNT. This is final, I am not interested in any discussion since you just use that to squeeze some money from people.
