Extremely dissatisfied with Coricraft

I purchased 2 couches in November and they were delivered on the 9th December. The moment they arrived I complained about the poor workmanship, uneven stitching on the seating and the arms of 1 couch was bigger than the others, the cushion on one couch was bigger than the other we had to constantly adjust them to keep them the same height. After much calling and complaining they asked me to go and choose another fabric as they were going to redo the couches. However when I get to the store the manager Risha tells me'the fabric I originally chose is no longer being used I have to choose another fabric which was approximately 9k more than I had paid. I instead under duress chose 1couch instead of 2 as everything else was above my budget. They asked me to use my existing one as a, loan until the new one arrived. However when I saw how poorly the new couches were in the 3 weeks we had them, the back cushions started sagging, the seats started creasing up i emailed Risha and said to cancel my order as I would like a refund. They uplifted the couches 1 month ago with no refund given. I email and call constantly as I'm out of pocket and out of seating in my lounge but I get promise after promise and yet to date I'm still waiting.
