App not working for nearly a week

I have been a loyal customer of Discovery since my first pay cheque and I have been so loyal that I will defend them agains anyone who, like usual has something bad to say about them. But my experience with Discovery Bank has been shocking and appalling to say the least and its a disgrace for a company of this caliber to give service like they do. My app has not been working for the last 6 days and this is due to a sales consultant that phoned me to assist me in joining a bank that I already joined. Long story short, this caused my app to have two profiles causing it not to log in. I have been on hold with their customer service department for hours then, I have sent 8 emails to *** and to a consultant called David without any replies. I even left Facebook messages without response.

You are a digital bank and I cant even use my banking app. Your customer service department is absolutely useless. I will advice anyone who is thinking of joining Discovery Bank to seriously reconsider .
