tangled.co.za ignore emails related to wrong product

Tangled.co.za advertised an iPad case with compatible iPad model number SPECIFICALLY mentioned in product description. I was willing to pay extra as I cannot find a case for that model iPad anywhere else. Forget the 7-day money-back guarantee - they don't bother to respond to emails regarding wrong packed and delivered products. I sent my first email right after I opened the courier parcel (well within the 7-day period)
