About BIJLIBILLcoupons by paytm

Hi dimers,
While browsing through Paytm I have seen coupons of BIJLIBILL1000, BIJLIBILL1500 and other type of coupon of bijlibill.
As per the coupon such as BIJLIBILL1500, the purchaser will get 1500 coupon for eletricity bill payment i.e. Rs.500 permonth x 3 months. And the the minimum trasaction / bill payment should be not less than 1000 per month
I was thinking, does paytm give cashback give full CB of 500 if I pay 1000 on electriciy bill.
And for more clarification I have called the customer care of paytm and asked about the CB.
And after having 25 mins of coversation (including there dialogues of “sir let me keep you hold for few moments” and “let me ask my senior” type) it has been concluded by them that they wont be giving full cashback but as per there term CB will b “upto 500” but only some percentage of eletricity bill and they went off.
And I was like uhh.. they shud have mentioned it in there T&C in full disclosure about it.
So dimers be aware of this BIJLIBILL coupon and do call customer care for more clarification before buying any product for getting BIJLIBILL COUPONS.
Just shared my experience. And all are welcome to share there experience about it.
