Nothing was too much trouble
"Thank you for organising this without me having to follow up.
I would also like to acknowledge how helpful and efficient you have been in this exchange. It can sometimes be stressful for a customer but you took ownership of the whole thing and did exactly as you promised as well as price match on the new item. Nothing was too much trouble.
Please don't underestimate how much good customer service means and you have definitely influenced me to use Sterlingbuild again and also recoemmend it to others.
So a big thank you from me and have a great weekend."
