I was surfing through mobile and from there i commited to buy a product , it was mentioned that the shipping is free within seller's city, I am from same city (delhi). Now when i initiate to pay by using computer the shipping charges add to the product value. By contacting customer care , and seller , the reply i get is that the pincodes are not mentioned in the system. now I donot understand why this thing has happened with me. and if i donot pay it is recorded as unpaid item which marks a negative feedback in my account. Why it didnot show before that shipping will be added. Its incomplete procedure.
