I sent a we-chat message to the landlord asking for his help. My landlord used to be a maintenance technician. He could fix everything and I’m a big fan of him.
As always, he took a quick action to investigate the issue on site. After that, he dialed the hot line and explained to the customer service lady everything except the model type because it was in <s style="background-color: rgb(255, 255, 0);">alphaets</s> letters and numbers. I was glad to offer help because it made me feel like I was participating in the project. Since I was a kid, I had a dream that I would be able to mend appliances at home.

Great work Kailin! I have made a few corrections to make it sound more natural.
The words in yellow are not wrong but don't sound natural so I have suggested the words in pink instead.
The blue is for spelling mistakes or missing words.
You could say "the company staff's schedule" or "the company's schedule" but you can't say "the company staffs' schedule" because that suggests there is more than one set of staff.
The words in orange "the truth was" are not wrong but don't sound natural so I suggest deleting them.
