Dear D&C,
I would like to formally thank D&C for the warranty work you recently completed on my aluminum fence. The fence was covered by the manufacturers warranty but I would like to express my appreciation to D&C for making all of the arrangements for the replacement, doing the new installation and following up afterward to assure that i was satisfied with the work.
My new fence looks great and thanks to your efforts it was a painless and pleasant process.
Please feel free to use me as a reference for your very professional work and results.
Sincerely,
Frank McKay
