Fuming with rage

I have never been so frustrated angry and irritated at the same time. Today I received a notification from TransUnion that my profile has been updated. when i went to check there is an account but the funny thing is that the credit card is not mine it for another Nedbank Client. So they updated my profile with someone else information who really has a an account at FNB. What I dont understand is how can one make such a huge error. I was in a process of an application when this happened. the most frustrating part no one is willing to do a follow up to rectify and rectify this I am told to log a dispute, when it is clearly an error on their side. I am so disappointed, to think that i really would stand for them when people tell such stories. I don't even want to mention the agents and unwillingness to go an extra mile.
