I am pleased to report that the noisy Virgin junction box on Holbrook Road that had been emitting a loud hum was silenced on Monday morning.
Yesterday, I received a message from Virgin Media, which they’ve asked me to pass on:
Thank you for highlighting the issue with the junction box in the Holbrook Road area of Cambridge. We have visited the junction box and have now silenced the noise caused by the power supply within the cabinet. We apologise for any inconvenience caused to residents in the area.
