Cracking Leather Couches

I purchased couches at Bradlows St Georges, Cape Town on 14th July 2018. I was told and also it was written on the couches that there were leather and was also advised to buy leather guard care which cost an additional R350. The total amount of the couches cost R19000. Now just after a year the couches are cracking on one seat and I realize these cracks are moving on to the other seats. I called the shop and surprisingly, although I have them covered by insurance, they don't help wear and tear but promised to come back with feedback. That was beginning of August. I stayed almost 2 weeks for their feedback until I made another call today the 27th August only to be told by the sales person that they have been busy! Come on people......this is supposed to be LEATHER!!!
