"Incorrect Text Message"

Today I received a text from the Heart Of Lincoln medical group informing me there was a referral letter for me to read. When I opened it, it wasn’t for me at all, it was for another patient in the surgery group. I felt awful that I had just read someone else’s private information. I feel slightly annoyed that whomever sent this to me didn’t look to check it was the correct name and address attached to it, and I feel anxious my information could be sent to someone else now.
