"Poor organisation"

I took my mother for an urgent CT scan. It was done the day after request, which was excellent, but it took a week for the GP to receive the results. They said they were faxing it immediately after she rang at 9:30 after waiting from Friday until Wednesday. The GP still hadn't received them by 2:00pm, and we rang them again and they said they were faxing them now. They eventually came the next day. In the meantime mum paid the bill on the day she was scanned, but they posted her the bill saying the money is due. This arrived in the post before the results were with her GP. She is 79 and the CT showed she had cancer. I just don't think she should have had to wait that long for the results when she paid to go privately, and to receive the bill that she has already paid while she was still waiting for the results added more to her stress.
