Poor satisfaction and customer experience

We purchased couches and they were delivered in March, within the same month we noticed a defeat in quality as the couch was floppy and didn't even enough material to maintain the shape and human weight and we logged a call. Indeed the couch was collected and repairs down however it came back with a whole in-between from better to worse and the 2 seater couch is also now floppy and not strong. We went to the store and we were directed to this email address

Question I have, why the couches are pricy yet the quality is bad How many times do we have to log a complaint to get a proper 100% fix Do we regret the decision to continuously purchase as furniture liquidation Customer experience has been compromised as since then no follow ups to check if we happy and what's the the next step

Last resort is for us to get a refund and let us go purchase a price fit couch else where as current the value and quality are not intact, I've sent an email to address my issue till todate no response

I have attached the pictures of the couch for ease of reference and hope for a best out as we can't be using our resources to get proper outcome
