Tata Motors — Wrong registration detail/backdated gate pass and service coupons

Address:

122018

Dear sir/mdm.
I have purchased tata zest xt reg no. Hr 26 ct 8617 on 15-nov-15 from aristo motors gudgaon. Invoice no.[protected].
They gave me a gate pass no.3367 dd 08-aug-15, where as i took delivery on 15-nov-2015, why i was given back dated gate pass and also they have issued me back dated service coupons dated 18-aug-15. Due to this date, i got call for servicing yesterday. This shows that the vehicle has been sold to some one else on aug-15 and all the papers were prepared accordingly.
Second thing i noticed that the registration of vehicle has been done as diesel vehicle and showing cubic capacity-1248. Where as my vehicle is petrol version and cc-1193. This all will create problem for me, in case of some miss happening.
My family is regular user of tata vehicle sumo, at present we have safari and tat zest xt.
