Zipker Online Services — zipker seller payment not received

Address:

Chandigarh, Punjab, 160047

I was a seller at zipker. They told me that the payment cycle is of 15 days and i started working with them shipped products as per the orders received on their seller panel. But no payment received till 1 month. Then i started asking for paymnets. They blocked my seller panel and stopped responding to my e-mails and calls. Where should i go? I have shipped prodcts worth rs 25000 but not received a single penny, they are a bunch of cheaters who are cheating the customers as well as sellers associated with them
