Mahindra XUV500 there's NO customer careFUL

Bought XUV500 W8 manual. Got in touch with customer care and in round about way told me that that it's my problem and that's it, wrote an email to Mahindra India and they not bother to reply. So to cut the story very very short as follows. 1, The infotainment system is supposed to be voice control, but the only problem it doesn't understand SA English, I have tried all different people to talk and NO it just doesn't understand. They told me to go back to technician and I did and they said they can't get it right, so I told customer care, and they say oh they report it to India and the end of that conversation. What the hell the car is sold in SA but it does not understand us.. On the same email my other complaint was that Mahindra installed a R 7 000.00 tow hitch which by the way was installed before they delivered the brand new SUV to me, when I coupled up my caravan and reversed the rear sensor don't switch off automatically and alarm keeps screaming till you take it out of reverse, NO BUTTON NOTHING to stop it. And on that one they rep**** I should have asked first before buying the car. Customer care should be called D.E.C. dead end complaints.
