Unorganised and unresponsive Westin service

We had international clients visiting and wanted to treat the to a stay in the Westin Hotel Cape Town. I phoned to make a booking and after 3 call directs finally spoke to a lady in bookings. We wanted to pay all costs involved and i asked for an invoice to be sent to me so i can pay before the guests arrive. I had to phone back twice just to get a bill where after i arranged that my colleague could pay apon check-in, they agreed. He arrived and they said the bill was paid. On Monday after the guests had left I get another bill which i pay. Then the next day they email saying whoops they forgot about some things and send another bill. <br> <br> Is this not a five star hotel which is supposed to be organised and not run by *********** people whom i have to practically beg for a bill and follow up for a bill, and then not know what is going on with their own booking and billing system?! <br> <br> This was shocking service.
