Its been more than a year, i have 15000/- reimbursement pending an no information when it will be paid, their customer service executives don't know anything about it themselves. No use of connecting to any mail-id or grievance department, never got any reply from them.
The company also changed to new name, does that mean the original company is bankrupted, are they cheating the mystery auditors.
Or is this how theydo business in general ??

original company - REDQUANTA CUSTOMER EXPERIENCE SERVICES PRIVATE LIMITED
new company - RETAIL QUOTIENT RESEARCH PRIVATE LIMITED
