Hi all!
This is my cover letter for a software technician job in the video game business
Thanks for helping me to find my mistakes

-----------------
Dear Sir or Madam,
I am writing to apply for the position of "F.O.G.S.A." as I find the position very interesting and appropriate to my ambitions.
I think my experience will be beneficial, indeed, this year, I worked as a maintenance technician for many companies because I was in temporary work but since March to September, I was a software and hardware hotline technician so I know the rules of a customer support and how it works.
Also, I think this job will be for me a great opportunity to combine my work skills with the video game knowledge I have. Indeed, video games are a passion for me specially online video games, which I have a very good experience by tested a lot of different MMORPGs, experience that is necessary to be a good <<reviewer? critical?>> to see how I can be more productive, more effective to improve myself and the service quality.
I am confident that my qualifications will be of interest to you, and I look forward to hearing from you, I am available on any dayweek for a phone call.
Thank you for your attention,
Yours truly,
X
