Welcome to the forums and many thanks for your recent post. I'm so sorry to hear that you've had a poor installation and that the cables haven't been buried adequately.
I've been unable to locate your account from your forums details to see if you've made any contact with us since Tuesday. If you haven't, please let us know and we'll be happy to look into this for you. As per goslow's advice too, any pictures you can provide of the state of the cables would be very useful for us to help provide the right support.
