I bought one plus nord when it launched(Aug 6th). I purchased it using hdfc Smartbuy link and also availed the no cost emi option through hdfc MoneyBack Credit Card. 
I took screenshots of all T&C and amazon transaction details.
It clearly says that the offer is applicable for no cost emi.
After 3 months when I checked with customer care, they says that the cashback is not applicable for smartemi options. They are saying that the transaction is converted to the smartemi.
But I used the no cost emi.
So please someone clarify is there difference between smartemi and no cost emi.
I know that the Smartbuy Cashbacks are not reliable, but even with all the proofs they are denying the cashback.

You should get CB, they are lying
SmartEMI: after purchase u login to NetBanking, select unbilled txn and choose smart EMI which is not No cost EMI
Interest charged is same as NO Cost EMI discount?
Their CC reply is so crude, mostly illiterates are operating: check=checked;consent=concerned;conformed=confirmed
and they are not clearly writing it as converted to SmartEMI
Reply to them that you will escalate it to Nodal officer and RBI
Recently I had to fight with YesBank for paytm cashback: Denied CB for txn done at 11.30PM on last day of offer,
1.tried to deny CB saying its already issued referring to similar CB for txn of earlier month
2.later rcvd email mentioning only that txn at merchant settled after offer date but funny they are not writing ‘CB denied’ I asked them to clearly mention CB denied as merchant settlement date is after offer date(I too had all SS) then they silently credited CB.
