Late pick up and dirty room!

Im a guest at Double Tree Hilton Upper Eastside in Cape Town staying for 31 days with them. I am appalled at 1) in 2 days now my room has not been cleaned, just the bed made and towels changed. The floors are dirty and the room still messy. Today i had arranged a pick up shuttle service, offered by the hotel, from Black River office park for 4pm. I waited from 15:50 only to be picked up at 16:35! All the time I was calling to enquire about the delay none of the staff bothered to apologise for this inconvenience, but instead passing the buck. It turns out that whoever was sent to pick me up, did not do so, another driver had to be sent. I got to my room to call their Careline, there was no response and I held on for some time. I called the Hotel Manager and even he or she was not available! Clearly Double Tree is not serious about service! I am staying here for 31 days and cannot even get my room cleaned well! This is shocking! I am appalled!
