Wasting my time and money - bad service & attitude

We purchased a Sealy bed from House & Home on 12 March 2016.At the time Tshidi promised that the bed will definitely be delivered at the end of the month.I called her on 29th March to find out when it will come and she indicated that it will be delivered on Friday, 1 April, which is a brand new month.On 30 March I called her for a delivery time, she said anytime after 9am on Friday. Since this is early, I missed work and waited for the delivery. At 10:15am on the so called delivery day, I called Tshidi and she said the bed hasnt arrived at the store and she doesnt know when it will come, it MIGHT come during the day. Why make promises you cant keep?Why make me miss work because you are guessing everything? She then said that they will definitely deliver it in the evening. My husband now received a call saying it will only arrive next Thursday. After promising end of March, you now tell me its coming in April.And dont blame Sealy,blame yourselves for your empty promises when you dont know anything.The service I received from you this past week is horrible and I want my bed asap, we paid a lot of money for it and late delivery cannot be an excuse for making us wait for almost a month
