Momentum BMW

Took my 7 series to check my alignment since my right wheel was inwards after hitting a curb. They claim to have done the alignment and told me i had a problem with the suspension, or knuckles that the right side looks lower than the other sides. Took it to Eurocar werk and as soon as he lifts the car he sees the tie rod is broken. Just wondering how they missed that and how can you perform an alignment successfully on it. They claim that it wasnt an alignment done and it was a diagnostic after showing me a alignment report. Even if it was a diagnostic where is the diagnostic report and why wont the fault detected. This dealership lacks trust and customer service. Advantage BMW did the alignment, brake fluid replacement and oil change and replaced the cabin filters.Talk to Mr Kuranoff the Manager, took 1 month and 3weeks before i could get the dealer's attention after numerous calls each week.
