My Statement Generating incorrect Account Name

I requested a statement using the ATM , put all my required details but statement reflect a different Account name yet the profile still returns all my details . I went into the branch to verify , info still returned an incorrect Account name . A call was logged on the 19th and reference number received and was told to check on Monday , i then went on Tuesday 24th was told issue is pending . I was told that there was an upgrade which went wrong but i find it hard to believe as this is not supposed to upgrade the database but rather the application . With such level of incompetence i wonder what effect it will have on the integrity of the customer database .
