Policy Bazaar — incorrect registration date printed on car insurance issued by policy bazaar

From last 20 days, i am chasing policy bazaar customer care to get my issue resolved. At the time of renewal of my car insurance, i provided previous year insurance along with rc but still due to policy bazaar staff's error, new policy i received carries incorrect registration date of the car. Correct registration date clearly mentioned on the rc (Registration certificate) provided at the time of renewal. From three weeks now, i am chasing policy bazaar customer service through emails and phone but not getting any solution. I also copied anjla (Senior director) @ "anjla. [protected]@policybazaar.com" thrice but no communication received from her as well. It seems my complaints are bouncing back. It is the worst experience i had with any online service i used till date. I paid the insurance fee in advance but when it comes to service policy bazaar is deaf.
