Bad Service

My hubby has a very bad experience with this company. They advertised a competition to win R4000 TruLock tiles on facebook and on 2nd September he was declared a winner. He tried contacted the sales manager who promised him delivery asap because the company was quite busy but till date there has not been a delivery. He has deleted the Facebook page and his account so the only way of communication is by telephone which he is not answering for the past month it goes to voicemail. The website still exists but there is no other contact details besides his and l don't know who can help him get his prize.
