To Whom It may Concern,
I have joined a summer plan with my friends from xx to xx. I was disappointed by the services provided. A staff member (xxx) from the spa unit even spoke foul to us which was in no doubt unacceptable.
Please do train up your staff members as their attitude do affect customers' impression towards the hotel and thus the hotel's reputation.
Thank you for your attention.
Regards,
xxx
