CMHT crapness

I have decided my CMHT are shit. Not necessarily the individuals working there (L is great for example), but as an organisation or whatever they are shit. 2 weeks ago they called me to say that L wasn't there that day and so my appointment was cancelled, and that she would probably be back the next day and would ring to rearrange then. That is the only time they have contacted me. I have rung twice since then and asked if she is there and been told she is still away, but they didn't ask my name or anything, so they don't know that it was me who rung, and that I know she is still away. So she has been off for 2 weeks, is likely to be off for quite a while longer, and the only thing I have heard from them is being told that she would probably be back the next day 2 weeks ago. I think that is quite shit to be honest. They haven't rung to say she is going to be off for longer than they first thought. They haven't rung and asked how I am, or if I need to speak to anyone else since she isn't there, and I usually see her at least once a week, or twice in bad periods. I have just had absolutely no contact. Admittedly, there is probably only one, possibly two, other members of staff there I would even consider talking to about how I feel, but that isn't the point. I just don't understand how they can decide that I need seeing weekly, and then not even call for weeks just because L is off. That seems strange. Either I need weekly contact, or I don't. Plus of course I was away the week before that, so it is now 4 weeks since I have spoken to anybody. It all seems rather inconsistant. It isn't L's fault - she is away, but I feel like CMHTs should have some kind of system in place for when a member of staff is going to be away for more than a week or so. I had a care coordinator a few years ago, when I was under a different team, who went off sick, and at first it was just going to be that week, then it got longer and longer, and actually she never did come back, but I was left for months with no support, after seeing her weekly. There is always someone on duty, but calling in and asking to speak to the person on duty is a lot harder than if someone calls and asks how you are. And it isn't even that, not having anyone to talk to - it is more that they haven't actually called to say she will be away for a while. I am not sure if I have unreasonable expectations in thinking I should be told my CPN is going to be off for longer than the day they originally said, or if they just are shite.
