Problem Landlord Advice

So since we moved in in January we have had serious issues with out landlord making trouble for us. When we arrived she would not come to meet us and we had to get an Air BNB and wait two days til she came with the keys to let us in. We did manage to have her move the lease start date to accommodate this.

On moving in we noticed that if you have the cooker on at the same time as any other appliance, turning on a 3rd appliance will blow the fuse. I contacted the landlord about this. I then got a phone call from her sister saying that she was the actual landlord and that she wanted to see rent in her account first. As I told her on the phone the rent had already been paid she told me that she did not trust foreigners (we are Irish) and that she would wait to check her account.

She told me an electrician would arrive the next Friday. He did not, he came the following Monday with no notice. I do not think he was an electrician, he arrived with a screwdriver and a pliers and nothing else, he didn't look at any of the electronics instead just turning on and off the cooker, cleaning it a bit, and then leaving. I got an email from the first landlord a few hours later saying that we just couldn't have too many things on at once.

We now feel that this is definitely not a safe place to stay and want to leave but know that the landlord will try screw us as much as possible in breaking the lease.

Is there any body in Brussels that helps tenants against bad landlords? If legal advice is the best course can anyone recommend a good English speaking lawyer that could help us and advise for free to start?
