Customers took to social networking site Twitter to vent their outrage at the blackout.

And @Dolls_N_Skulls also tweeted on Saturday: "@virginmedia still no service in south woodford! Sort it out Richard!!!"
A Virgin Media spokeswoman said: "One of our cables in the Seven Kings area was damaged by construction work carried out by anothe party.
"Our engineers were on site within the hour and worked around-the-clock to bring everyone back online by Saturday afternoon.
"We apologise for the inconvenience whilst the repair work was carried out."
