Crocs South Africa do not care about their customers

I ordered and paid for 5 sets of Christmas Jibbitz. The order was delivered on 5 December and one set was missing. I emailed Crocs South Africa, who indicted that I would get feedback within 24 hours. This did not happen. I have now followed up with them 4 times, as these are intended as Christmas gifts. Tinus now 23 December and there has been no resolution despite their promises.
