Was my tone bad?

Or was I being too blunt?

Last Sunday I booked an appointment at a spa in the Da'an District

I cancelled because something came up at the last minute

Then today, Wednesday, I booked again via LINE

The customer service rep replied with an attitude that didn't feel very nice, saying "You cancelled on Sunday, and now you want to book again?"

I said I would arrive on time and not be late

Only then did customer service arrange it for me

And I completed the session

I left a LINE message thanking the therapist for the service; it was very relaxing

The customer service, being very pragmatic, sent a heart and said, "Please also help us give five stars on the review site…"
