Frustrated by Collision Management Centre

I'm so sad that as a customer I'm not getting any response from CMC. After being advised by them on what to send of which I made sure that by the 12th of February 2018 they had all they required but they haven't came back to me. On Monday the 19th of February 2018 I called their office to find out about the progress of my claim, I was told to leave my number then they'll get back to me but until today I haven't heard from them. As a paying customer who has never been in arrears I find this very frustrating.
