When signed the contracts, only half year later got SPA. Not balcony rail material indicated inside SPA. Of course, CGDB can say you can do anything not inside SPA. But all the ads (displayed model, ads videos, what sale said) showed the glass rail on balcony. Now change to metal rail, is it cheating or not? I am not one to anti china developer, I was first one to support CGDB project and bought one at first opening of the project. If you search what have done Country garden in china, you will know how bad CG cheated the owners. Just simple search website.
Another one is about the inductor cooker. The showroom showed the label of standard spec. on the inductor cooker. Now CGDB changed it to gas cooker. Any owners of CGDB may just call your sale about the issues about the inductor cooker and balcony glass rail. CGDB ads
