These Guys Are Posing To Be From Original Agarwal Movers And Packers. Some Mr Sandeep Provided Quotations In Initial Discussion While After Picking Up The Luggage, They Have Sent Inflated Bill Of * Times Of Original Quote. There Was No Evidence Given For Weight Of Consignment.
Now Mr Sandeep Is Not Reachable And Someone Else Is Talking Saying 'Forget About Discussion With Sandeep, You Have To Pay The Bill'. They Are Taking In Very Rude Manner Not Providing Any Details About The Amount. They Just Added Insurance Amount Which We Had Not Asked For.
Overall Not Getting Any Support, Worried About Our Luggage Which Is With Them Which Is Worth *, **, ***.
Luggage was picked on **th March and it is not dispatched yet. As per the original discussion, the total payable amount was **** for dining table and chair and Rs **/kg for remaining luggage. But they have now charged the amount for dining table and chairs twice, as **** plus for weight as well.
We have still paid INR ***** as per the discussion of **-** payment terms. But these people are now not shipping the luggage saying first pay ***% amount. We are really helpless since our luggage is lying with them
These people talk in a very rude manner saying if you want to go to police you can go but 'seedhe tarike se kaam nahi hoga'.
The website mentioned on their bill also doesn't open and mail sent to them also getting bounced

Only contact available is for Mr Sandeep - **********, Mr Mohan **********.

We want our luggage to be delivered ASAP and the extra charges taken for Dining table and chair (additional Rs ****) to be returned.
If not possible, please return our luggage and refund the Rs ***** which is paid to them
