smartbuy yono doubts - along with gv cashback eligible ?

Any one clarify this plz’

In yono, u will get 5% cb on the amount which is charged on sbi card. U can partially pay with gv also but u will receive cb only on amount paid by sbi card and not on product price

i have never actually tried doing partial payment in smartbuy but i am guessing that smartbuy will give you RP or cashback based on the amount paid via hdfc cc/dc and not the actual total amount paid for the order.
i am guessing this because smartbuy always says in t&c that price of any product will vary on the merchant site and we will get RP/CB based on that, also it never actually accounts for how much affiliate commision is earned by the order, they just give the promised RP/CB even if they get only 10 Rs and they have to give 1000 Rs cb for that.

will smartbuy or yono – gives their 5% cashbacks if used HDFC or SBI cards along with Amazon/Flipkart gift cards ?!
::Yes

in smartbuy,
Flipkart, only HDFC related cards payment available, no gv.
:: Check in Desktop its available
for Amazon it has to enter card details in smartbuy site, and can use Amazon app. so gv can be used in payments, but will get cashback ?
:: Yes, for the amount paid through HDFC card

in yono,
all bank cards and gv are available, but SBI cards lead to get cb, what if we used along with gv ?
::Yes, for the amount paid through SBI card
