Delhivery / Ssn Logistics — undelivered parcel

I had ordered from www.latestone.com and the order was shipped through delhivery courier vide tracking #[protected] on 2nd sep, 2018. It was expected to be delivered at destination in surat (Gujarat) on or before 5th sep, 2018. Today is 12th sep and i have still not got my parcel. It was laying at delhivery surat office since 4th sep. Nobody attempted for delivery and i continued follow-ups but as usual i got only one answer that we have escalated the issue and all the stuff. For last 3 days delhivery started a new technique and they updated status as out for delivery first and then in the evening they used to update as consignee not available.in fact no attempt was made to deliver the parcel and i do have cctv cameras at my factory gate and i can prove that the status updated was fake and misguiding. The same practice they are applying for last 2 days.in fact yesterday on 11th sep i got a call at 5:30 pm from a delhivery courier person and he informed me that your parcel will be delivered within half an hour but surprisingly i found the status update as consignee not available in the evening. To be very frank i must add that delhivery people are just playing with persons. They do not understand the seriousness of the items ordered and their deliveries.
