Good morning @Appleblossom that's great that you felt 'seen' and well cared for yesterday. Sorry I'd lost track of the fact you already had a plan approved and were waiting for it to be issued - is that correct or do you have it and it's not up and running yet? (Too focussed on my own stuff recently). Has anyone helped you go on the myGov NDIS portal at all? Or have you had a go at it yourself? When your plan is first approved the NDIS sends you an access code so you can access it. Then you set up your own password etc - or if you've ever used myGov for e.g. medicare or centrelink you will have that already. Your plan may well be on there already but not sent to you also or not sent to your CoS (just a possibility I thought of). That's where you set up your account details for your transport allowance to be paid into too. That should be backpaid to the date your plan started. If your nominated CoS still hasn't contacted you I'd be getting really impatient so well done that you're managing to be patient, especially considering your son's situation with them as well. I'd be humbugging them in your position. Hopefully the LAC has given you their direct phone number or at least online contact details and you will have more advocacy from them on your behalf.
On the NDIS website somewhere there's a list of NDIS service providers in different locations and what services they do. You could find some alternative CoSs there to enquire with and maybe choose one of them to go with. You have the right to do this. "CHOICE and CONTROL"!
Are you plan managed? I am and it's worked really well for me so far. If you are plan managed and have chosen someone to do that you might well be able to start booking your own support workers through Hireup or there's another one called Mabel I think - that have freelance SWs - you can interview them too before using them. (You don't need a CoS to use them). If you want to know more about this you can ask me. I use a small company and they are prompt, personal, and good communicators.
I don't know where you are (Tassie rings a distant bell) but I recently joined a community disability alliance group that's all PWDs helping each other and have been put in touch with a peer mentor who's had NDIS funding for 5 years. She is a mine of information and very encouraging and confidence boosting about my rights to things like changing CoS, and how to go about it. Maybe there is such a group where you are that could help you get your plan up and running despite the lack of active CoS.
Sorry if the rave is too much this early in the day!! If none of these suggestions are relevant to your situation just ignore them ... no need to respond why....
Hope you get some action soon. NDIS can do a thing called 'escalate' your case which might be worth asking the LAC about. Might also be worth getting a receipt no. every time you have a call with them, or even doing things by email so there's a paper trail if it gets to the point you have to do a complaint.
Hope today is a good one for you and you hear from the LAC and are able to put all this stuff to rest and trust that people are doing what they say they will on your behalf. In case it isn't obvious, that's a huge bugbear to me, a number one button pusher.
