Cohen's Fashion Optical review: lack of service

I purchased glasses from these people back in feb of 2015, i thought nothing of i at the time as i needed glasses and was told they were reputable little did i know. Since feb i have been back frequently to get adjustments as these lenses are too heavy and doesnt seem like they were made right and they tend to give me a headache due to he weight on my nose. I contacted cohens to let them know i was displeased, they suggested i see someone else in the store for an adjustment. She was a headache by itself. She was rude, unprofessional and tightened my glasses so much i cant wear them. It took her 45 min to adjust them i dont think she knew what she was doing in the first place, even though she claimed she did. was doubtful! This is a horror of a company to deal with, i want an exchange at this point. I will never waste a single dime with them again.Taking to their customer service is also a challenge, they simply dont care.
