Customer care non existent

I was offered a loan from Discovery Bank, but when i supp**** all the relevant documents i received a letter of Decline. This letter has amounts on that is totally wrong, and when "challenged" i just receive the same letter again. I tried numerous times to get hold of a consultant, but the app seems ineffective to authenticate me.

I tried to send a email to mydispute@discovery... But had no response.

Discovery seems to have little to no customer care.
