Poor product with poor service and no follow-up

I purchased a R350.00 Redken Hair Product from a local Salon that had a horrible effect on my hair opposit to what it claims to do. I contacted the Salon and received no positive response and thus I decided to contact Redken directly. On Monday 7th December I called the South African Branch. I was directed to Chris Evans at Customer Service. I explained my situation and he said he would need to look the product up and then get back to me. Five days later and he has not followed up at all. Each time I have called in, the receptionist has been rude, abrupt and distracted. She keeps putting me through to Customer Service, whereby each time I have called, no one answers the phone. I have left four messages and have not yet been contacted back. Today I asked her to put me in touch with another Manager and she refused. She said I need to speak to Customer Service but as I explained to her, Customer Service has not responded for five days. I was then told that no managers are in the office. It was 8.30am. I understand from the Voicemail Service at L'oreal, that L'oreal is open from 8am? This looks and feels like the staff at L'oreal are giving me the run around.
