Bad service and breach of promise

I purchased couches on the 6th of September and till today I'm still waiting, 3 months have passed and they're failing to deliver my couches. The Sales consultant ignores me when I call or send messages and the manager is referring me back to the consultant when I complain about her bad service. They said the couches will be delivered between 8-12 weeks, 12 weeks have passed and they ignore me when I ask for refund so that I can purchase a couch somewhere else. They don't update you about the progress of your goods while you're waiting for that 12 weeks to pass, they keep quite even though the time frame has passed. The manager is Jane and sales consultant is Cynthia. Today Cynthia decided to pay attention to me when I tell her about consumer rights. She is asking me to give her more time and she can only offer me a "loan couch" in the mean time. I told her that I want the couches that I paid for or my refund and she continued to ignore me. Please advise, what can I do to get my money as they have failed me as a customer?
