Western Dental Services review: crown teeth

I went to western dental for crown teeth.This crown was suppose to be on for 15 days but they keep making mistakes for 3 months.it is suppose to be 2 weeks.after that i purchased the most expensive crown teeth, the tooth was horrible and ugly It had a different color than my other tooth's.the doctor convinced me to sign a form that i agree at all terms that the doctor did a very excellent job, the form is not related to western dental policies.at 1-13-12 i had paid the total payment for my crown teeth but they keep informing me and calling my house every single day from the collection deportment .when i went to western dental to do the correction, when i spoke with the supervisor named Cindy she was so rude and very unprofessional to fix my problem. Cindy didn't fix my problem she just ignore me as a patient.i don't recommend west er dental i had a very awful experience . and still the problem continues NOW!
