Tropical Optical

i had a bad experience with tropical optiocal, went for an eye exam and it costed me $80 for the exam. but few days later called the office to let them know that one eye need more power but was told because i did not buy my contact with them , would have to pay again.no call back , nothing . The service is the worst, tropical optiocal should not be in that business and i hope the cityt of chicago would look into this business . DO NOT GO THERE ,EVER.
