Kind assistance in a difficult situation

To the friendly lady (in the first office as you walk into the branch, sorry I didn't note down the name). <br> <br> Thank you so much for going the extra mile in assisting me to get my challenge resolved even though your branch was off line when I arrived there yesterday afternoon. <br> <br> People like you who go the extra mile in assisting customers really do brighten my day!<br> <br> Without your assistance I would have been in a world of trouble. <br> <br> Thank you!
