More than two week wait - unsuccessfully - for a spare part

I took my Samusung Table for a screen replacement. I have no problem with any business finding it difficult to get parts, because it is an expensive part that would not normally be kept in stock. But they have been promising to get it fixed "in a few days" for more than two weeks. And now they want to "order it from China" which I told them two weeks ago I did not want. DON'T keep customers dangling.... just tell us the truth,
