Poor workmanship. Terrible Investment

Bought a brand new apartment off plan and 3 months after moving in my floor tiles started popping up. The same thing happened to all the units in the complex and the developer took responsibility but they’ve done nothing to fix the tiles. Shower wall tiles are also delaminating and can fall and break anytime while someone is in there. Can’t walk comfortably around my own home for fear of breaking the tiles. Can’t put the place up for rent as initially intended because who wants to live in an apartment with broken tiles? Terrible investment, very unprofessional company with poor workmanship. They definitely cut corners and now the investors are paying for it.
