Bad service and broken promises

I contacted Inspectacar Lifestyle in Centurion regarding a 2018 BMW 520d. I visited the dealership to view the BMW and for them to look at my trade in. I dealt with Immy the owner/manager and we agreed on a deal. I then sent my docs required and the next day they tell me they have another buyer so they cant for the deal. Nobody called me to inform me I had to call Mike and Jaundre (sales guys) numerous times. Inspectacar Lifestyle just don't care. STAY AWAY DONT DO BUSINESS WITH INSPECTACAR LIFESTYLE
