Faulty item email for item purchased on 1st July 2019!

Ok this has to be a record for us, customer has just used the item and found it to be faulty 2 years, 7 months after purchase date.
Have said if they return the faulty sheets (they are stickers) I will check and if faulty I will replace, know I didn’t need to do this, just wanted to give them good service.

Anyone else had faulty product emails older?

Thanks for reading
