Useless Oakleys South Africa

I bought a new pair of Oakley sunglasses last year from The Pro Shop, and within months the lenses started peeling on the inside. I took it back in March this year,and they were sent back to Oakley. Oakley then came back and said they received the glasses,but no invoice,I know the guy sent the invoice along,he showed me proof as well. Since then they have given us numerous email addresses that nothing goes through to. We have tried several times and they just say they can't help us over the phone, we need to email this address and then give us another useless email address. I own about 20 pairs of Oakley sunglasses, but this is definitely my last pair.
