Impossible to close a Discovery Bank credit Card account.

Discovery bank has the inability to open emails or answer calls if a client wants to close their account. First I tried to close my Discovery credit card account. That process fell over and then the account (my old card expired in March) automatically migrated to Discovery bank. This, after Discovery Card agreed not to migrate but close the account instead. Now I apparently have a Discovery Bank account (the account details I do not know). It seems impossible to make progress. When one does pick up eventually on ***most cannot help for some reason. The ones that appear to try are unable to. Discovery Bank does not respond to emails nor are they eager to answer calls. They even let you know their official email inbox is not monitored. Nor do they monitor their email address nominated for sending your completed cancellation form - they even told me this on the phone. For the man in the street the bank is not worthy to be called a bank. Steer clear of this entity!
