rewrite this in a profession way "Dear NAME_1

I apologize for any inconvenience caused by my absence from work. I want to inform you that I have been hospitalized for the past four days due to a medical problem. Today is my first day back at work, and I am gradually catching up on pending tasks.

Regarding your refund, I understand your concerns. I will personally follow up with the relevant department tomorrow to ensure that the refund process is initiated promptly. If you do not receive a copy of the refund by early next week, I will personally ensure a full refund is processed for you.

Once again, I apologize for the delay and any frustration this may have caused. I appreciate your understanding and patience in this matter.

Best regards,"  Make sure to only use capital letters in your entire response.
