Sunglasshut

Purchased a pair of Holbrook sunglasses for 2800.00 rand .the warranty lasts for 2 years.as soon as the warranty ended ,the sunglasses developed bubbles on the lenses.I think it's ********.its called planned obsolescence marketing concept. I am unemployed and can't afford 2800.00 rand every 2 years.sunglasshut told me it will cost me 1000.00 rand to get sunglasses fixed.
