Not acceptable

We brought a PU leather lounge suite from Cielo Lifestyle at Greenstone mall 2 years ago. The fabric on the suite went brittle within a year and started to crack very badly - i contacted the store who then referred me to the Wheco Group - the kindly exchanged the suite for me - but not even a year later 2 of the chairs on the new suite are doing exactly the same thing, so i contacted the store again who told me to deal with the manufacture who are The Calgan group, they then told me that they don't deal with end users and i must deal with the store and that the store would handle the whole thing , and this kept going back and forwards, eventually the store said that the suite is no longer under warranty because my original purchase was 2 years ago - but the new suite is only a year old and is doing the same thing, we paid R18 000 for this suite and i cannot begin to imagine what it is going to look like in 5 years time. Now nobody wants to assist me, they are just ignoring my emails and brushing me off. I have asked that they just replace the 2 seats that this is happening too, they don't have to replace the whole thing. i am so angry and don't know what else to do - they are completely giving me a miss - i feel that this is unacceptable and that they should replace these flawed products, . www.calgan.co.za / www.wheco.co.za / ***
