MP/s & Councillor/s. Can't they really help, or it's just that they're not interested?

I contacted the Liberal and Labour Councillor and they all are the same... I wonder exactly what they do and can do! Because, from the feedback I've been getting from all of them, neither of them can't do anything to help me. I've even written to the Lords, but I was told there too, to escalate my complaint to the Local Government Ombudsman - that they are the only people/organisation that have powers over the council. But I got another bigger shock when I found out the LGO took the council's side even though the council is wrong. The LGO didn't even do their own independent investigation, they just looked at the council's report and agreed with everything the council stated, even where the council is wrong. None of what I stated was taken any notice of, nor acknowledge - it was just as though I didn't send anything to them. The LGO investigator didn't even contact me for further evidence to support my complaint against the council. In fact, she didn't even inform me when she'd completed the investigation until nearly 2 months later when I contacted them to find out why I wasn't contacted for more evidence to support my case. All this I sent to my MP, but he didn't even bat an eyelid to any of it. What I've seen from the LGO decision is; the council is right even though they are wrong, and I'm wrong, even though I'm right. I'm told that the situation I'm in, is not just the council at fault; it's mainly the government because it's the government's HMO scheme (a substitute for lack of building council homes) and the (Labour) council is just carrying out the (Tory) government's orders. Therefore, I can see why this Tory MP is not interested in helping me out.
