Asus India — Misleading display boards and horrible after sales service network

Address:

Faridabad, Haryana, 121006

We bought abovesaid cellphone through flipkart in november 2015 at 920 sector-9 faridabad, haryana 121006. but to our dismay the software of the handset got crashed/hanged and it is not at all working. despite making several attempts at asus customer care on 17th march 2016 .
but in the end we were advised by the customer care executive to approach their service centre at gurgaon, panipat or karnal available in the state of haryana.
according to asus customer care pickup policy is also available but 50km onwards only.
1. my serious question to countryhead marketing asus zenphones is why you people have put on your electronic display boards in the entire faridabad and ballabgarh region when you have not got any service centre in this particular fardiabad and ballabgarh region ?
2. isnt it a malpractise of buisness/unfair trade practise?
3. when you have put on your display boards in any particular region have you ever mentioned that you hold no service center in this region in case of any complaint relating to your handsets mobile ?
4. when approached different shopkeepers displaying your asus boards they were simply laughing and showing their inablility to answer why the company has put the display boards on their shops?
would you please come and throw light on your marketing/misleading strategy?
