Pathetic Service from BMW

Pathetic Service from BMW My husband bought me a MiniCooper in November 2017. The sales consultant that was helping us was Swe Ngcobo. We told him first time we buying a car that we want the car to have stripes(black stickers) both in front and the back which he promised that he would get that done. He called us on the 1st December 2017 to put the stripes on, when i collected the car i was soo upset that the stripes was only infront and not at the back. He promised to call me regarding that issue which he hasn't. I went to BMW during December he advised me that he is waiting for the guy that put stickers to be available. I waited until this day. Yesterday on the 23rd January 2018 i went to his office, i asked him that ive been awaiting and im not getting any help. The attitude he gave me was soo arrogant and despicable. I asked him does putting stickers and getting service takes more than a month and he said Yes confidently. Im soo upset and very disappointed on the type of the service i got from BMW. Its like he doesn't care about customer service because he already got a sale and his commission. The installment that we pay every month is way more than the service we getting. We really hope that will get the sticker stripe corrected soon because im not getting any joy!!!!!
