Pathetic service and no items received

@sleepmasters I have purchased a based and mattress on the 28th Nov 2020 and when I received the item on the 30th Nov 2020 it was defective. The following morning I lodged a complaint and received a sms stating my items will be delivered on the 15th Dec 2020. As the day of the 15th progressed I called again to find out what time to expect the delivery only to find out the delivery is not planned for that day. Received another sms saying the 17th Dec 2020 I can expect deliver and again nothing arrived only to be told delivery will happen on the 18th Dec 2020 and again nothing arrived. I have called the store to complain as well as the call center and none of which are able to escalate the matter of give me any answers. I have been taking time off just to be present for deliver, time and money of which sleepmaster is not compensating me for. I still have not received items and the complaints department refuses to escalate the matter.
