Potential Zomato fraud!!

I usually order from this restaurant but since a month the distance from my address to this restaurant is showing as 7.4kms, while in reality it is 5.4kms. this results in a paid delivery even after zomato gold. I mailed zomato about this quite a few times but they say they'll look into it but don't take it forward. Is this a scam? I know 3 resturants with the same address issue.
