Microwave plate takes FOREVER!!!!!

My husband accidentally broke our Samsung Model: MS143SCE microwave plate on Friday, 12 June 2015. On Monday, 15 June I ordered a plate from Nadia on ***. She assured me that the plate will be ready for collection from Germiston on Wednesday, 17 June, latest Thursday 18 June. I called on Wednesday, Nadia said it wasn't there yet. I called on Thursday, the plate still hasn't arrived. I called on Friday, still no plate. On Monday, 22 June I spoke with the Branch Manager Cecile or Cecelia and she promised me that she would personally guarantee that the plate will be there on Tuesday. I called on Tuesday, NO ANSWER!!!! I called on Wednesday, 24 June, still no answer.<br> <br> I have 2 small boys, not having a microwave is not acceptable!!!<br> <br> Coincidentally my Samsung washing machine broke on Monday, 22 June. I'm just saying...
