Hello, Ibrahim -
I hope I am correct in thinking you are asking about an electric shaver. If so, this is the link for the Remington Products Authorized Service Dealers:
http://www.remingtonproducts.com/support/where-to-buy.aspx
You will need to enter your US Zip Code in the proper search box to obtain a list of authorized repair businesses.
If you do not reside in the USA, then go to the Remington Products Contact Us page:
http://www.remingtonproducts.com/support/contact-us.aspx
Use the form on that page to send an email asking about authorized repair for your shaver.
