Dear sirs,
Against my purchase vide bill number 8278/5 dated 21/09/2018 through reliance retail limited, ground & first floor, 32, jagat banerjee ghat road, howrah-711102 (Wb), i was entitled to get the free assured gift (5l pressure cooker) but the same was not given due to non-availability (One due slip has been given). I was assured to be contacted as soon as it is made available.
But till date neither any call has been received from their end nor they can be contacted (In the given number [protected]).
Kindly take immediate action to resolve the issue.
