Terrible service at Woodlands incredible connection

I received terrible service at your Woodlands store. This is against the customer consumer act reguarding exchanges.I have proof of payment and the package. I purchased a pair of headphones. The one ear is faulty just 2 months after the purchase. The manager Lydia refuses to assist me with a new pair. I explained to her I use these daily and can't wait for 14 -12 days. This is poor service no one told me this is the policy! These headphones have a warranty on, nowhere does your policy clearly say you must hand them in if faulty and that there is a waiting period. Your slip at the back also doesn't stipulate this policy.I request assistance
