disgustedby the service i received from transunion

I sent through my settlement letter of one of my accounts to them to that they can update my information accordingly. this was the 3rd of December 2015, after a numerous calls today the 18th December 2015 I get told the letter was not the way they want it to be, I mean it had all the information they needed to update but no, they needed more. so I got another letter and send it through. should I have not called them, when were they going to tell me all that, and now certain things are going to be delayed because of their stupidity of not thinking of sending an sms or call me informing of what they needed to do their job. I'm a tremendously disappointed and concerned because these are the people who are responsible with our most valuable information. They could actually send through wrong information about a person just because of their own ignorance and of which could cause someone their life\ worst case scenario"...this is highly unacceptable and I will definitely take this further."""
