Turn around time

I logged a claim on the 24th it said successful and book in at the assessment center for 27/11/2017 at 8, when i came there they said they could not find the booking. I then called in from the assessment center to re-book. The call dropped and the consultant did not phone back . I called back again and logged the claim. the assessment was then done. The assessment center said ill get a call on the day or early the next day. I still have not received a call. I then called in and was advised that ill get a call on the 29/11/2017? I am not happy with the handling and speed of this claim.
