Discovery Bank Can't comunicate

Discovery Bank thinks we can read their minds. They bombard me with SMS's and Emails saying I still need to send them the additional documents. No more info, nada. I have sent it more than once and received a reply that agnollage the receipt of the documents but the SMS's en email does not stop. It turned out I sent the wrong month's bank statement. but They don't bother telling you what is wrong just spam you to send the wrong additional documents again. This is seriously terrible communication from Discovery!

They do the same with Discovery Insure. If you have 2 cars and each car have a tracker in but the one is faulty, they will just tell you you need to repair the tracker, but not specify which tracker. They will send the message over and over but not give you what you need to do something about it. Not even a reference number or phone number
