Discovery Bank - an UNBEHAVORABLE bank!

Last year I tried to switch my Discovery credit card to a Discovery Bank credit card. This I could not do as the Discovery Bank app is not compatible with my Samsung J1 phone. Last month I upgraded to a Samsung J3, the app is now compatible with my phone. For 3 weeks I have tried to sign in on the app, but could not finish the process. Reason: the automatic scanning of the drivers licence does not work! I called the bank over this period and spoke to 3 different consultants. The first one said I should scan the drivers licence with my printer/scanner and email it to an address given to me. Nothing happened, nobody contacted me. On 10 Feb I spoke to consultant AJ, who asked me to send the email for his attention. He promised to contact me, by this morning nothing happened. I called again and spoke to Phathu, he promised to get someone to call me. Just after lunch AJ called and we went through the sign-on process on the app. As soon as I got to the scanning step (he suggested I scan my ID), nothing happened. I tried it under various light and background conditions. After this he said an IT guy will call me, which did not happen. I agree with the many complainants, that this bank app is useless! I suppose I will never become a Discovery Bank client. The service sucks!
