Delhivery — Delhivery is exposing sellers personal details to other sellers

I have serious data privacy issue related to your first mile delhivery portal i.e fm.delhivery.com. If I login to fm.delhivery.com as client I could see other seller's details like personal address, phone numbers everything. That means my details also exposed to other sellers as well. My Personal data should not be exposed to others sellers. I should see my data only. Kindly take serious necessary action as early as possible without fail. This is a big concern of Data Privacy. In their privacy policy no where it is mentioned that one seller can see other seller’s details. I have already sent an email to them they have not taken any action. They are saying it is not a privacy concern.
