Very disappointing service and attitude

I've ordered R17000.00's linen for the guesthouse from their company who promises a 10 day delivery. Of course I had to pay the full amount immediately.In 3 days it will be a month that I've been waiting. I get no updates on the reason for the delay and repeatedly has to send emails.When I finally spoke to him on the phone today, he was very rude and told me they were very busy and it might be sent on Friday, which of course means that it will take some more time before I receive it. I was supposed to understand that they were very busy with other clients in crisis and that I will definitely eventually receive my order. It really upsetting if you expect good service and get brushed off as being difficult.
