Poor customer service

I went to Northcliff auto today, as warning light came on my vehicle. I knew it had something to do with the day time running lights bulb, I asked Marr-Ann if I could speak to a technician , to simply establish if I could replace the bulb myself or if it was more difficult to replace, and if I needed to book in the vehicle. This lady barely acknowledged me and mumbled to have my key. She printed out a paper and confirmed it was a daytime running bulb that need to be replaced. And pointed me to the parts department, I asked her why I need to go to parts as I need to establish with a technician if I could replace the bulb myself or if I needed to book it in. She simply rep**** that they would help you, I walked down to the parts department and spoke to a coloured gentlemen he was extremely helpful and tried to assist me. He confirmed that Marry-Ann was supposed to check with a technician as he can only give me a price on the bulb, regardless this gentlemen got up and walked me to a technician. The technician was also extremely helpful. he explained that a wel cover needs to be removed in order to replace the bulb and that it needs to be booked in. However, I needed to check with a service advisor on how much the labour would be. Walked back up to Marry-Ann, she simply looked like she wasn’t interested or like she is doing me a favour. I asked her how much the labour would be and she got up not telling me where she is going and disappeared for about five minutes to the back, she came back and mumbled that it would be about a thousand rand labour to replace the bulb, not even giving it to me in writing. I have bought 4 BMW's from Nothcliff Auto through the years and was about to purchase a new one shortly. I will never ever again purchase a vehicle from them again or refer any of my friends or family.
