Bad communication from cielo

We bought 4 Halo chairs and we're disgusted in the quality.2 chairs bubbled and we contacted customer service to replace the chairs. They collected the chairs on 11 January and we got no communication from their side. We had to phone them regarding when the chairs will be replaced. They need to manufacture us new chairs, why? If they have it in stock at the stores. Finally received a tracking number from ITT couriers on 2 February, when we wanted to track the parcel there was no tracking number in their system. Dealing back and forth with Renuschka at customer care and there's still no answer as to where our chairs are. They are still trying to find out what's going on. We have to keep phoning Cielo for updates. You guys really need to work on your communication. This is such bad service.
