It was extremely frustrating when I arrived at 7:30 am for my 8:00 am MRI (as instructed by the text message reminder), only to be turned away because apparently I was supposed to be there at 6:45 am. It is completely unacceptable to give patients incorrect information and then penalize the patients! If you are going to utilize a text message reminder system, the information needs to be accurate!  The staff was very understanding and sympathetic of the situation and instructed me to contact someone in the MRI department, which I did. The staff informed me that this has happened to multiple patients, but the problem has not been solved. Do better, this is unacceptable.
