Biggest mistake to buy Renault!!!!

Got our Renault Duster 29 Nov '14. On 18 Jan'15 the driver door mechanism got jammed and we cant unlock the door.Took to dealer to find out a part must be ordered and can only be here 3weeks down the line.Due to work we cant wait this long and its a BRAND NEW CAR!!!!After numerous calls to HO and the dealer,they found a part and eventually could replace it today...just to hear its the WRONG PART!!! HOW? SURELY THERE IS ONLY 1type DUSTER IN SA!!!! For 3weeks been climbing over to passenger side to get out. BIGGEST MISTAKE OF OUR LIFE TO GO RENAULT! I want to get this car off our name as soon as possible and NEVER AGAIN!!!!<br> Maybe a banner over the N1 stating our severe disappointment in Renault, their service delivery and incompetence will create awareness of this.<br> Should have read all the complaints on hello Peter before we made this decision.<br> Hope other potential buyers read this and change their minds!!!!!
