Dear Sirichai,
I am writing to sincerely apologize for being late to our meeting earlier today. I understand that my tardiness caused a significant delay and was a major inconvenience to you.
The reason I arrived late was due to an unexpected mechanical failure with my car on the way to the office. Unfortunately, it took nearly an hour for the roadside assistance team to arrive, and during that time, my phone battery died, leaving me unable to contact you immediately.
Because of my late arrival, we were unable to finalize the design specifications for our upcoming project within the scheduled time. I am aware that this has pushed back your own deadlines for the afternoon, and for that, I am truly sorry.
To ensure this does not happen again, I have already arranged a full service for my vehicle this weekend. Furthermore, I will make it a point to leave for the office much earlier for our future meetings and will always carry a portable charger to stay reachable in case of any emergencies.
I would like to suggest rescheduling our discussion for tomorrow morning at 10:00 AM if you are available. I am more than happy to adjust my schedule to suit yours.
Best regards,
