No after sales satisfaction and service delivery

We had purchased a prw owned BMW 6 months back @ R349000. When we purchased it the front head light was cracked and was told its OK and nothing will happen. Every time the car gets washed the headlight fogs up which in due time will cause some electrical fault, we also noticed a fog light cover is missing and the bonnet is not aligned Took my wife's vehicle for a service amd made it aware to the service lady, she said she will get back to us regarding the issues but since then never received any feed back. She also stated that she would make arrangements for there panel's hop to align the bonnet. Still nothing to be heard. I will now go directly to BMW SA, IT'S TOTALLY UNACCEPTABLE
