Homechoice is abusive

I have ordered a bedroom set from Homechoice telephonic ally, approximately 3 to 4 months ago and I have not received it. however i get calls from them everyday asking me the same question which is "have you received the goods?" my answer is always no. and the consultants hang up the phone with no further advise or surety that the shipment is on the way. I receive SMS's weekly stating i should pay whilst i have not received the goods. they have even escalated to send threatening sms's stating they are going to take harsh action against me if i don't pay the stipulated amount of the initial order. i would like homechoice to stop harassing me, as I'm now seeking legal assistance for their atrocious customer s****s.
