Could someone pls correct my grammar? (10FEB)

Hello everyone, Could someone correct my mistake again?
Thank you so much

Q:
You cannot go to a company where you got an offer. Write a letter to the HR supervisor to
1. Explain the reason why you decline the offer
2. Express you gratitude
3. Explain you like your current job very much.

-----------------
A:
Dear Sir,

I am so grateful to receive the offer as a customer service executive form your end. I am satisfy to the benefit and salary which offered, and I feel that's my pleasure to work in your company as well. Unfortunately, I am sorry to inform you that I am not able to accept your offer.

I like my current job very much since my company provide a very good environment, also the company's policy is also very nice. Moreover, the company will move to my hometown so that I don't have to driver two hour per day to go to work anymore, that's the main reason to let me stay the company I am working right now since I have to take care my children everyday.

Thank you so much for your understanding, I will be looking forward to work for you later.

Regards
Assman
