Kent RO — Kent Gold Smart - 11017

I have placed a service request as the water was not getting purified.The Service engineer came and replaced all the parts ( uf membrane and two filteration parts)and I paid him Rs[protected] for the parts and 300 for servicing cost). During the servicing the engineer misplaced the auto cut part and has said that he is not having the part but will come and repair the same when he gets that part.But the engineer is not taking my calls and I am stuck with an additional issue with my Kent filter.Have attached the servicing details.
