bad service by application department

This has been by far the worst experience I've had started work in March and we are required by the employer to have gems medical aid so I put in my first application and the sent me back and forth saying I have missing documents till my application was cancelled.

I app**** again for medical aid around the 30th of June and have on countless occasions tried to contact their service center where I was told that my application could not be processed because of outstanding documents which I then sent through on the first account.I then received another notification saying I have outstanding documents after I had sent all required documents, I then called to find out what documents were outstanding and found that the very same documents which I sent previously are still said to be outstanding the consultant then acknowledged receipt of my documents and said they have escalated them to the membership department and they will get back to me. Today again I get a message saying my application has been cancelled when I call they tell me that its because I didn't put in my bank branch code on the application when they have a branch code with them on the bank statement they requested.I am so angry I can't believe I had to wait 2 months to be told that my application is still not processed.This is terrible service at its best.
