Toyota — Harassment by company employees

Address:

Kolkata, West Bengal, 700107

This complaint is against Topsel Toyota at 719, Anandapur, Kasba, Kolkata.I visited the showroom's Used Car section on 6th August, 2016 and spoke to Mr Suman Kumar Deb and saw an Etios V which was pretty much to my liking.
I was asked to come over today(7th August) for a test drive of the car. Mr Deb said he will not be there and introduced me to and gave me the business card of the procurement officer Sourav Paul. I called Sourav at 2pm & he asked me to come over. Upon reaching the showroom with my family, Sourav Paul told me that no test drives happen on Sundays. More importantly, his approach and behaviour was extremely impolite and filled with ignorance.
I asked Sourav to call Mr Deb which he did and came back to tell me that the car can't be taken out of the showoom premise & I could try it out inside the premise!
This seemed absurd to me and I felt like I was being joked with!
Upon calling Mr Deb myself, I was told the same thing. The shocking part was that it was the same man who told me to come less than 20 hours ago!
I came to the ground floor & complained to the Asst.Manager and was completely ignored. Thus we walked out of the showroom
I'm wondering whether the utter disrespect and high-handedness I received was because I went for a used car or is this the way Toyota treats its prospective customers?
