SweepSouth - unprofessional service

On 27 August I booked a 4h cleaning at my 2 bedroom 1 bathroom apartment for 31 August at 08:00. On Friday the so called "sweep star" was on her way and at about 07:30 I was informed that she was running late and would be delayed by 45 minutes. At 08:45 I still haven't received any updates at which stage I had to go. After about 2 hours I phoned SweepSouth and they only then informed me that their "star" was not going to make the appointment. To make up for the "misunderstanding" they moved my booking to Saturday 1 September, and surprise surprise the "star" did not arrive on time and an hour after the appointment she closed the job. I again phoned SweepSouth and they informed me that they are not going to be able to honour the arrangement.
