Why do businesses enjoy to write apology junk mail to customers? if a product is faulty Answers: It's a short time

if a product is faulty

Answers:
It's a short time ago good customer service. My boyfriend found a piece of plastic within a pie he bought from Sainsburys so I sent it back to them and they sent an apology dispatch and lb15 worth of vouchers. My faith is very soon restored in Sainsburys and I will shop near again. If a product is faulty, it is their "fault" (haha) and hence customers would like to receive an apology.

To avoid individual sued ?

As far as I know a business does not have to write an apology communication if a product is faulty, however, if they want to appear concerned more or less their customers remaining customers, and if they want their customers to know that they value their business, consequently they will write an apology letter. It's not other about the simple exchange of money and products or services, sometimes customers want to be more than a number.
