Mahindra And Mahindra — unnecessary change of spare parts

Address:	Chennai, Tamil Nadu
Website:	Mahindra service centre(India garage)

Hi sir.my vehicle suddenly got stopped on running on 9/7/18(Monday)at 8:00pm approximately in alandur, chennai.i don't the reason for that, my instrument panel indicator shows check engine light.i called the on road assistance, they came&check the vehicle, they checked the fuse, fuel&he suspect a problem of air lock, so he loose the fuel filter assy screw&he pumped the fuel filter assy the diesel came out&he started it's get started &within moving of 300mts the vehicle stopped again&the check engine light shows.so we towed the vehicle to the INDIA GARAGE, guindy, there they checked the vehicle &they tell we can check only morning, we have to plug it to laptop&check, so I stayed in a hotel.in morning I got a call from the service centre &they asked what happened, I explained them all the details they said we will check&I went to the service centre within one hour from the call.they said that want to change the FUEL FILTER ASSY bcoz of leak, 15litres of diesel as there is no diesel in tank, fuel tank floater bcoz it's showing wrongly.
My doubt is that they changed the fuel filter assy bcoz of leak in that&diesel spilled out in fuel filter assy, I had a doubt here only bcoz while we pumped the fuel filter assy as mentioned above, the diesel came out&it got spilled out at that time itself, so on considering that diesel spilled out I think they changed the parts, if so that was happened by the assistance team, they only pumped &diesel spilled out.
On conclusion I want to know that there is an really leak in the fuel filter assy, so only vehicle doesn't starts, or the vehicle is run out of fuel.
I asked to them the reason they said there is a leak, there is no proper explanation.
If the diesel was not there in the vehicle as they said, why the voice command has not came, my fuel gauge shows it's of 1/4tank.
I want to recheck up my changed fuel filter assy for the leakage problem.i want to know if vehicle was called on road assistance, if there is no fuel, we have to pay for that r they have to pay.
I need an genuine explanation from Mahindra regarding this issue.i am asking this bcoz I have recently done my 90k service in Mahindra on 26/6/18.u can check the service history, my vehicle was periodically serviced in Mahindra.
Personally I lost hope&trust in mahindra.all the service centres are only money minded, they changing the spares as of their wish, if they need money from the customer
