Poor Service

I am shopping for a car and I saw a BMW X3 xDrive 20d SAV A/t 2019 model 7599 km for 649 900.00 on the BMW website and I sent a query and a log was created for BMW Rustenburg to contact me. However, on 15 February I decided to call personally and after about 7 attempts with my calls dropped by staff members who were saying they are transferring me, I spoke to on Sipiwo lady about what I am looking for. She promised to return my call within 30 minutes and she never did. Today I called again I spoke to a certain gentleman who advised me that Sipiwo was not at work today, he can transfer me to her cellphone or he can assist. I have discussed with him what i am looking for, and he also said he was going to call me shortly, it has been more than an hour and I am not sure what is the problem with the salespeople in that dealership or maybe i do not meet criteria for their clients, which i don't mind, but they must tell me so.
