Bad Service Provider/Contractor

In March 2015 my husband, myself and our son moved into a property which was new but had a few maintenance issues that needed attention. The contractor has sorted out certain issues but not all of it. We are left with no one getting back to us as it seems that they bluntly just don't care of our concerns raised. We've been sending a number of emails and they are selective when it comes to responding to emails. It's been more than 2 months now and we're still waiting on answers or a resolution to our request. It's been very unpleasant and stressful having to deal with this contractor and between our jobs and seeing to our 1 year old son we can't always send out emails or contact the contractor. That being said the contractor appears to be nonchalant regarding our requests. I'm in the process of taking further steps by contacting the ombudsman as I believe that there are in violation of our rights. We just want them to abide by the contract we have signed and to honour our requests.
