"I don't get call backs like I'm promised"

I have been trying to use this service on behalf of my mum. 

I understand the service is stretched and busy but I work shift work and have been spending my days off on the phone trying to get ahold of people who are meant to help but do not, I don’t get call backs like I’m promised and just keep getting pushed from GP to mental heath team on a loop and no one will listen to me. 

I feel it need to be made easier to gain contact with these teams and actually stick to any promises being made! 

I am exhausted from all of it! How much do I have to kick and scream before anyone will listen to me, I still haven’t had my call back even though I ring multiple times a day to remind them!
