Refuse to refund

On 2/2/16 i purchased a bahy sense wrap, my baby refuses to be put inside, she is not the crying moaning type. But put her in the wrap and she screams like hell. Returned the wrap, the area manager and store manager refuse to refund me saying its not a manufacturing defect... The CPA states that an item should be fit for use or fit for the intended purpose. Called headoffice they refuse to authorise a refund... Is baby city in financial trouble? It seems they are if they refuse to do refunds. My rights as a consumer has been violated. I purchased another baby carrier from pep, also took it back with thr same complaint, they refunded me with no problems. Manager and regional manager johan are both rude and arrogant... I want my R400 back!
