SBI — credit card payment

Address:

713103

Hi,
I am sankarsan bhattacharya from burdwan, west bengal. Recently, i received sbi-bpcl card (Card no-[protected]). While advertising the card the sbi representative, mr. Nabakumar communicated me about 2 major benefits of the card regarding fuel purchase. They are, reword point benefit and the wave off fuel surcharge of 1%. The first bill has generated today and it includes 1.8% of extra charge on petrol purchase. Initially mr. Nabakumar repeatedly assured me that those extra charges would be wave-off in bill. Now, he is not receiving his phone. I raised the matter to the customer care of sbi. They are saying that i have to pay the extra charge anyway. The wave off benefit on fuel purchase is still mentioned in the sbi website.
I have taken this card to get both benefits, reword point and surcharge wave off. I have to pay rs. 499+gst for these benefits yearly. Now if there is no fuel surcharge wave off then why should i pay the full amount? Besides, mr. Nabakumar assured me that, i can redeem my reword points in any bpcl petrol pump of burdwan. I went to all bpcl petrol pumps in my town (Burdwan, west bengal) and none of them have this facility.
As you can notice, i am not getting almost any benefit through this card and now i have been forced to pay this amount. Please look into the matter and do the needful as this is a matter of credibility.
