"Nottingham county south crisis team"

In the past I have had some really good support from the crisis team but, in the past month or so, it seems impossible to speak to anyone. When phoning, I constantly get the answerphone. If I do leave a message, my call isn’t returned. This is despite phoning a few times a night. I feel that I have no where to go for support during crisis times in the weekends and evenings. The other evening ended in some very unsafe behaviours and 999 which, I believe, may have been minimised by talking to a mental health professional. I realise every service is stretched but this team seems completely inaccessible.
