[protected] — Fraud toll free number

Found this number [protected] online registered as Samsung help center. I called the toll free number thinking as Samsung authorized dealer but they are not and lied to us by saying it's Samsung help center.
They tried to rectifying the repair and changed some parts and charged me around Rs 4500 without bill eventhough chasing for it for week but no use.
My problem with washing machine is not resolved and they are rude in answering from where they came all clueless.
[protected] is the number of the guy.
