Mega Cabs — Uncooperative driver with no knowledge of drop area

I had booked a Mega Cab on 7/11/2015 WITH ID -KOL0118 The cab no-9456 with cabbie GOURANGA TANTI reached the destination more than 40 min late. I was travelling with my aged grandmother and he was uncooperative as ever.He wouldn't even come forward to pick us up. Furthermore, I was not aware of the routes and surprisingly neither was he ! He kept complaining about the fact that i didn't know the way and I had to constantly put him in touch with someone who knew the way. My father had to leave work to come and show the way. Finally he took a long turn and charged us a lot. I reqest mega cabs to not send such drivers who don't know the are and are plaIN RUDE.
