This is regarding community centre
I have booked a community center for my marriage. But due to some issues my marriage has been postponed. So
I have cancelled community hall before thirty days. I have submitted all the documents at sdmc office rajouri garden on dated 21-10-19 and the gave me the receiving on same dated with their stamp. As per your terms and conditions if i cancelled marriage hall before 30 days den u will cut only 20% amount. But still i am receiving only 50% refund. So please sort out my issue
