RCS cards, closing of account

I have I account with RCS and tried to close my account. When I phoned (I was placed on hold for 10 minutes) I was given a settlement amount to close my account and the banking details to use when I make to payment.

The banking details I was given was incorrect and I phoned in to get the correct banking details/ arrange for another way to close my account I was put on hold for another 20 minutes and they dropped the line.

I found RCS to be quite helpful when I opened the account but when I tried to close the account they try to make it as difficult as possible (I assume so that are forced to keep your account open and keep paying the monthly fee).
