Delhivery — Company not paying us COD amount of Rs.55,467/-

Dear Sir/Madam,

We are an ecommerce company and we service our clients through various couriers. One of them is Delhivery B2B. There are few invoices which are COD. The customer pays the courier company cash on delivery of the parcel. The courier company then in turn is suppose to transfer that money to us within a space 2-4 days. Since last 2 months this company has stopped transferring us our COD amount. The total of which now is Rs.55, 467/-. The details of which are in the table below:

Total Amount to be paid to Sumegh Supplies Emart LLP 55, 467

The company has stopped responding to our emails since last 1 month and they responded twice on twitter 2-3 days back but now they have stopped that too.

It seems the company is in a bad financial shape and is not paying us our money. and is using that money to pay off their outstandings.
What are my options?? Please guide.
