Pathetic customer service

Please help..... I purchased a bed last month already.. paid the delivery fee and o was promised that the bed would arrive the following week. It didn't! I went in n again they said the following week. It still didn't. I went in yesterday and the area manager said he will deliver it today even if he has to do it himself. Surprise surprise today still nothing. Went in again today and again he is saying tomorrow. Is that fair? Is that good customer service? I'm fed up of fighting over something that I paid for. I do not want a refund I want my bed coz I have paid for it!!! Please help me to sort out this issue. It happened at kings comfort diamond pavilion mall in Kimberley. The area manager who made all these empty promises works in the warehouse in Bloemfontein
