UPDATE:
I came home from work today to find a package from the spa at my doorstep. The package included 3 sets of body lotion, shower gel, hand cream and a bar of soap in small tote-bags, along with 3 20% off coupons for our next massage (must be used before March 15.)
There was a hand written note that said "
We hope you enjoyed your spa time with us. We apologize that you did not receive your gifts at the time of your visit. Please enjoy with our compliments."
There was also an e-mail:
"Thank you for taking the time to share your thoughts on your recent visit to The Spa. We value your business and regret that we did not communicate your service times clearly in advance.
The Spa gifts have been shipped to you, we sincerely apologize that they were not given to you at the time of check-out.
I was out of the office and I apologize for the delay in my personal response. I would welcome the opportunity to further discuss your visit, please call me at you’re convenience.
Regards,"
I'm really glad that I mentioned the free gifts.

The "
regret that we did not communicate your service times clearly in advance." tells me that maybe I misunderstood and that scheduling is not necessarily written in stone?
I tried calling back, but she had already left for the day and I left a message. When I do talk to her, I pretty much just want to say what was written in my e-mail. I'm not looking for additional compensation.
Any words of wisdom for what I should say?
