ISAZISO ESIBALULEKILE - SICELA UFUNDE NGOKUQONDA
Abathengi bayaqonda futhi bayavuma ukuthi abathengi banesibopho kuphela sokukhethwa nokusetshenziswa kwemikhiqizo namasevisi e-Artery.
Imikhiqizo namasevisi e-Artery ahlinzekwa “NJENGOBA INGABE” futhi i-Artery ayihlinzeki ngeziqinisekiso ezivezwayo, ezishiwoyo noma ezingokomthetho, okuhlanganisa, ngaphandle komkhawulo, noma yiziphi iziqinisekiso ezisikiselwayo zokuthengiselana, ikhwalithi egculisayo, ukungaphuli, noma ukufaneleka ngenjongo ethile maqondana ne-Artery's. imikhiqizo namasevisi.
Ngokuphambene nalokho, abathengi abalitholi ilungelo, isihloko noma inzalo kunoma yimiphi imikhiqizo namasevisi e-Artery nanoma imaphi amalungelo empahla yengqondo equkethwe kuyo. Akukho mcimbi lapho imikhiqizo namasevisi e-Artery ehlinzekiwe ayohunyushwa ngokuthi (a) ukunikeza abathengi, ngokucacile noma ngokusikisela, i-estoppel noma ngenye indlela, ilayisensi yokusebenzisa imikhiqizo namasevisi ezinkampani zangaphandle; noma (b) ngokunikeza ilayisensi amalungelo empahla yengqondo yabantu besithathu; noma (c) eqinisekisa imikhiqizo namasevisi enkampani yangaphandle namalungelo ayo empahla yengqondo.
Abathengi ngalokhu bayavuma ukuthi imikhiqizo ye-Artery ayigunyaziwe ukuthi isetshenziswe, futhi abathengi ngeke bahlanganise, bakhuthaze, bathengise noma badlulisele noma yimuphi umkhiqizo we-Artery kunoma iliphi ikhasimende noma umsebenzisi wokugcina ukuze usetshenziswe njengezingxenye ezibalulekile (a) kunoma yikuphi ukwelashwa, ukusindisa impilo noma ukuphila. idivayisi yokwesekwa noma isistimu, noma (b) noma iyiphi idivayisi yokuphepha noma isistimu kunoma yiluphi uhlelo lwezimoto kanye nendlela (okuhlanganisa kodwa kungagcini nje ngamabhuleki ezimoto noma amasistimu e-airbag), noma (c) noma yiziphi izinsiza zenuzi, noma (d) noma iyiphi idivayisi yokulawula ukuhamba emoyeni. , uhlelo noma uhlelo, noma (e) noma iyiphi idivayisi yezikhali, uhlelo lokusebenza noma uhlelo, noma (f) noma iyiphi enye idivayisi, uhlelo lokusebenza noma uhlelo lapho kubonakala khona ukuthi ukwehluleka kwemikhiqizo yoMcibisholo njengoba isetshenziswa kuleyo divayisi, isicelo noma uhlelo kungaholela ukufa, ukulimala komzimba noma ukulimala okuyinhlekelele kwempahla
