Lack of delivery and correspondence

Hi we selected our furniture over a month go at the Centurion branch and paid for it on Tuesday, delivery was promised to be made yesterday 14/12/17 no one came to deliver the furniture and no one bother to phone to explain why no delivery took place, when we try to call the phone just rings and goes to voice mail this we found with all the branches as we tried to phone all of them. My parents are over 60 years old and have sever back problems now they will have to sleep on the floor tonight as they sold their bed and will not break a promise like Decofurn Centurion does. We spend over R 28000 with them the biggest mistake ever.
