Here is a Sample Apology Letter for Incorrect Information. You should modify this apology letter according to your need and situation.
Little Star Hotel,
I am writing this letter as I am in the need for the proof of stay in your esteemed hotel for the duration of five days. I need that proof as I could claim my travel and stay allowance from my company in which I am working. But, I have noticed that the address is not the same only when I heard from you that the information furnished by me in the hotel reception while booking the rooms for reservation of rooms was incorrect.
I am bound to explain you that it was not made intentionally. It was just an accidental mistake that I have let my friend to deliver the receptionist with my details. The problem was caused due to the fact that my friend actually doesn’t know my new address as I have shifted from my old residence to a new residence of different location only recently. As he was not aware of my new address, he gave all the details which correspond to the old residence of mine. Also I didn’t ensure the details when I have signed in the hotel register while checking in. I accept that the mistake of not verifying my address specified in your billing counter is entirely mine due to I was staying there for my holiday trip.
Hope you could understand my position and need for a new bill in this regard. I request you to kindly accept my apologies and provide me a new bill.
With Warm Regards,
