After sales assistance

Bought a Nissan Livina XGear March 2020. I got the car and heard a noise when steering. I advised the sales rep as he confirmed "if there are any problems please don't hesitate to call". This is within two weeks. I advised him of the problem and he said its lock down and will not be able to assist now. Then lock down level changes and i advise again on this problem. The customer care department send me then a mail that the call is logged. After investigation they came back to me and advised on rejection reason. "Please see Invoice terms and condition “wear and tear” clause 2.2.1 – 2.2.5 signed on the 14/03/20. As per the Report , your request falls under the wear and tear clause and we are unfortunately unable to assist" Its the invoice i singed to collect the car so in lock down my car stood at home and just from standing there got wear and tear??? Really??? The after sales assistance and mechanical warranty i took for the car is non existing and are only for making money in my opinion. I called and send more mails to complaint but did not even get a respond. I didn't have the car even for a month and its wear and tear. Please do your homework and make sure you get real mechanics to check the car before you buy or sign any papers. If you signed they just wash their hands and its your problem. Very bad service. I would never deal with them again or refer anyone to them.
