Reliance Industries — Non processing of return order

I have been pursuing with Ajio for more than 2 months for processing a return which is stuck due to mistake at Ajio's end, despite escalation of issue to grievance officer, no action has been taken due to which my Rs 1600 are stuck with Ajio. Till now I have talked to 10 executives and 7 supervisors but they all just keep raising complaints and then mark that complaint as resolved without even resolving it. I never faced such problem with Amazon or Myntra
