Re phone entry system Hyde Court, Parkside, Waltham Cross. Several weeks ago the phone entry systems started making an extremely loud buzzing sound. This was reported. The noise stopped therefore I assumed it had been fixed. No, now we cannot let people in using the system & have to walk down the stairs to the main front door. This has been reported several times & I was informed that this would be fixed. It hasn't. I have disabilities & struggle with the stairs. Please will someone rectify this. It took you ages to rectify the rat problem we had & now this. The security lights are also not working either.
