Try this
- Name what was corrected, such as replacing an item or updating a wrong booking.
- Confirm whether there is anything still outstanding. Avoid using gratitude to imply that an incomplete repair is finished.
A worked example
“Thanks for correcting the reservation. The new confirmation has the right date, so that part is sorted.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If a cost or inconvenience remains, discuss it directly. Recognizing the repair does not require pretending the mistake never mattered.
