Order didn't arrived as promised\ still waiting

Good day,

I bought a Samsung washing machine dryer combo from Dion wired Hyde park on Monday 30-04-2018. I was told there was no stock at this store however this would be sourced and be delivered on Wednesday 05-05-2018 which I can then come pick up. I phoned Wednesday and asked If I could come pick up the Item and was informed "it will probably be here tomorrow" I then asked to speak to the salesman which was not available and was told he would call me back which he didn't. Today 03-05-2018 when I called to enquire I spoke to Logan (salesman) from Dion wired which informed me that I can come friday afternoon 04-05-2018 but couldnt confirm a time. When i told him I need a time as later afternoon will not work for me he said i must come saturday..

I was promised that I could pick this up wednesday originally and therefore bought this product and now i'm being told i must come Saturday. I feel like I was **** to..I could've gone to another store and picked this up by now.

Thanks
