Shiprocket — Wrong RTOs Initiated

We are the shippers nirvapate.com
We have 3 orders RTO initiated without any reason. The end customers never received any call. Shiprocket didn't even inform the reason why RTO is initiated after waiting in their hub for 3 weeks. Money deducted for shippement and return. Huge loss for both shipper and customer.
Shiprocket never answers the call. the customer support number is just a fake number. They ask us to wait for 5 mins and the call gets disconnected in 2 mins. Fraudulent company. The mail reponse is given after 2 days with a predefined template apology. No action is taken.
