Maruti Suzuki Alto - Irrelevant call

Dear sir,
I frequently receive calls from maruti suzuki call executive asking me whether i'm some hazarika, kalita, ali, ahmed, sarma, saikia etc or not and whether i own a ciaz, dzire,alto etc car or not. i indeed own an alto k** car and nothing. moreover, by profession, i'm a simple asstt. professor, head of my department in a govt. college, and a ph.d. guide under the constituent university and after taking over all such responsibilities, i don't remain in a mood to face such unnecessary and irrelevant calls in my number **********. may i therefore, request you earnestly to stop those unnecessary calls! i further would like to request you to kindly organise your digital database by keeping my name only against the aforementioned alto k** vxi car. at least, for a company like maruti -suziki, it won't be too difficult to maintain the database in connection with seller -purchaser relationship. thanks and regards,
dr. dip kr. bhattacharjya.
