As per your agreement provided to me, seems that the agreement date is 25/12/2014 not 30/12/2014. Why the BG date is 30/12/14? As there will not have any liability to be raised for period from 30/12/14 till now, can they also accept the BG with the issuance date instead and NCR may provide another a letter to cover from 30/12/14 till now?
BTW, can we make payment to GSB instead?
