DESPICABLE SERVICE!!

I bought a tv unit on 02 February. the delivery date was 5 February. 3 Feb, i've received an sms and a call about the delivery. I've told them the delivery date should be 5 Feb. 4 Feb, i've called and asked if they could deliver it that day since i was at home. They promised me that they would. This never happened. On 5 Feb 14:00 i called Game to enquire about the delivery. i was told the driver had my unit and was suppose to deliver it. The person i spoke to said he would come in contact with the driver to double check. When i called back, i was told the driver's phone was on voicemail hence he could not double check. At 16:30 i've received a call from the manager, who admitted that they made a mistake but the unit would be delivered tomorrow 06 Feb. i refused point blank. i then instructed the manager to ensure that i receive my unit today still. At 18:30 the unit was delivered BUT still in it's box. When i asked why it was not assembled i was told that it is a DIY. why was i not told about that? On top of it the driver became aggressive when i refused to accept it or sign for it!! i am very upset to say the least!! i need someone to sort out this please!!!
