Damaged mattress

I purchased a queensize Restonic mattress from Homechoice on account during November 2017...Very soon after delivery i contacted them because the coils in the mattress was hurting my back...it was not even necessary to lay down on the mattress to feel the coils...you can feel with your bare hand....i was promised that they will send out someone to come and inspect the mattress at my home....after a few days and still nobody who came out to inspect the mattress, i phoned again....same story....after a few days i phoned again....still no joy...on 29 December 2017 i went to Homechoice in Wynberg and insisted to speak to a supervisor who can assist...a lady came and informed me that she could see on the system that i have phoned numerous times and she could see that each and every time someone did make a note but no action was requested....she promised that they will send somebody after 17 January 2018 from Restonic to inspect the mattress....but they will contact me beforehand....since 17 January 2018 i have phoned twice already...still nobody came out! And in the meantime i have to pay for sleeping on springs!!! Homechoice does not care about customer service or about any inconvenience caused to customers...they cant care less if you hurt your back on a faulty mattress....im done phoning them...im going to court
