Yash bhai I purchased F198 drone with online payment ie prepaid payment but I never said that customer will be charged ₹99 for the delivery I applied promo code also where I got ₹ 100 off , but again for free battery I need to pay again ₹99 for the battery, ur executive said either I will get free delivery with coupon code or free battery, but as u said for prepaid order will get free battery ,phir mein promotion apply karo ya na karo usse toh koi fark nahi padna chaiye
