Dear sir/Madam

That electric Scotty's controller did not work properly so I called the authorised dealer to repair it because it was under Guarantee period. So that dealer took controller and assured to return back with in 7 days but 1 month already passed away still the dealer have not given that controller. I called the dealer many time to send a guy to repair the scutty but he did not send a guy till now give. Service is very poor. I tired by calling the dealer and now I am mentally harased. My mob no [protected]. Please resolve my issue as soon as possible.
