PATHETHIC SERVICE- FAILED TO DELIVER

On the 17th december i placed and fully paid for a bed at sleepmasters online. (Order No. *** for NS KHUMALO ) Following day they sent an sms stating they will deliver on the 4th January 24 i immediately called them n sent email to cancel the order due to urgent need of the bed stating i will opt for another shop. They responded with sms's changing delivery dates to 22/12/23, on the 20th i was sent an email stating order is shipped and on the way. But it was not delivered i have been calling and emailing with no assistance. Its either they deliver or refund immediately because they acted smart by changing dates bluffing me and still failed to deliver.
