Halalbooking Has Ignored My Request to Correct Hotel Booking Dates

I made a hotel reservation in Hurghada, Egypt, through Halalbooking for September 1–5. Although we actually planned to stay at the property for only three nights, I accidentally selected the wrong dates and paid for four nights through the booking system. I notified the company as soon as I realized the mistake.

I also sent screenshots of our flight tickets and clearly explained that we had two separate flights, which meant the reservation dates needed to be corrected. I requested a refund for the one night we would not be staying. Despite this, I have received no response for three days. I have been unable to get an answer by email or through any other communication channel.

For reservation No. 4159252, I request that the booking dates be corrected and that I receive a refund for the one night we will not use. I also expect a written response as soon as possible.
