I
have joined in the service of Smart Infosolutions Pvt. Ltd., Dhirubhai Ambani Knowledge City, Navi Mumbai, on 24/06/2003.
On 01/04/2005 I have been transferred to Pragati Value added Services Pvt. Ltd.
On 01/05/2005 I have been again transferred to Reliance Integrated Services Pvt. Ltd., Dhirubhai Ambani Knowledge City, Navi Mumbai.
I resigned from Reliance Integrated Services on 30/09/2016 and they settled my dues including PF for the period I was in the service of Reliance Integrated Services only.
When I contacted them for my earlier dues, I was told that they do not have any idea about Smart Infosolutions and Pragati Value added Services. I have not received Gratuity also for the period I was with these companies.
I need my PF numbers of both Smart Infosolutions and Pragati Value added Services for withdrawal of PF and for getting Scheme certificate for applying pension.
