Red Taxi — Driver unnecessarily took long route and cab fare was double the actual

Address:

936A, periya kenaru street,, 3rd Maruthi nagar, Ammapet

Hi My contact number is [protected]. I have been a regular customer of Red taxi.

On 04/04/2022, I booked a Red-taxi ride for my guests who was new to the city. The trip was from my home (Periyakenaru. ammapet) to salem new bustand which is typically ~8kms and usually changed ~Rs.150

Booking ID: SB404UMYHOTD
Driver Number : [protected]

I confirmed with the driver that he knows the route to new bustand before the trip starts. The issue was, after the trip started he asked my guests if they knew the route to new bustand when they said "No", he bluffed some execuses e.g. This route there will be more school autos and took long by-pass route which eventually get charged Rs.288

First of all, when he knows the route, why he asked my guests whether they knew the route?
Why he didnt inform the route will be longer and it will be charged extra?

After seeing the fare, when I called him and salem -Red taxi office, he bluffed some reasons and ensured he would pay me cashback of Rs.150 because of his mistake. But his number is not reachable post that.

I would need the cashback and I dont want to encourage this behavior. Moreover it gives wrong impression to "Red Taxi" and I & my relatives have to stop using it if I dont get the expected solution for this.
