The customer can save themselves from such crooks from taking them for granted. Whenever we come across such service providers, always visit their office, take id proof, and do not pay at least some money by cheque so that in case of fraud, their addresses can be taken from the Bank. Apart from mobile number, ask for landline number too and some references, copy of I-card, driving licence, pan card etc.
The owner should submit the servant verification form with the police himself and should not believe the verification conducted through the agency. We should ask some local contacts of the servant apart from the name and contact number of his/ her past employer (s) and should verify the past ourselves. By taking these precautions, we may save ourselves from some big mishappening though this may delay the process but will save us from a big hazard.
Registration of placement agencies should be made mandatory and local police should also make it mandatory to inform the ownership details to the local police station.
