Problems with Discovery app and some staff

I app**** for an account but in three days nobody could assist me to login. (.keep on telling me “invalid”. After several calls, frustration and three days later I decided to go to another bank and remove the discovery bank app. Very POOR. ONLY 1 person named Beauty tried but couldn’t help. This is not a friendly app and it seems that some staff are not trained well enough to assist. Not even worth trying again. Dissapointed indeed!!
