Jimmy Choo My 28th birthday present, my first JC

Did you have a problem with the quality of these? I bought the bello version off Net-a-Porter and the back heel cap bit lifted off after only wearing them on carpet for a couple of hours. I returned them straight away and against my better judgement asked for another pair, the same thing happened again! AUD$425 and they are faulty. I have never seen such a shoddy manufacturing detail. Such a shame as I really love them. Never buying Choo again!
