Exchange or money back

I went to Bradlows on the 6th of March to ask for an exchange of the bed that i bought last year...till to date i haven't received the bed whenever i call i am told that they will bring it...the bed is paid up but it's giving me problems...i have never skipped a month on the payments...i was told by the head office that exchange was authorised on the 12th of March but till to date it hasn't been delivered to me...where am i suppose to sleep meanwhile because the bed is uncomfortable...is this the level of service that i am suppose to get...no i don't think so...i am the customer and i am not attended and according to the Consumer Protection Act this is not the way to treat customers...are they treating all the customers like this???
