Wires galore!

Hi, I wonder if anyone can point me in the right direction  - I'm tearing my hair out with frustration!!  Some months ago, various improvement works were carried out in our street, including the installation of new electricity/telephone cables whilst we were in the UK.  The new cables have been attached to our property (not an issue) but the old ones are there - hanging off the house, a real tangled mess, cut through and tied to our window security bars and are, quite frankly, an ugly, dangerous mess.  I've contacted the council a few times who've just ignored me. What can I do!
