Virgin Media has been accused of leaving holes in the walls and not as a result of complaints to repair the damage.
One customer said that he has so far waited six weeks to have a 10-inch crater in its plaster repaired.
The complaints of social media often say that the requests for phone calls or web chat with Virgin I have gone unfulfilled.
Virgin Media has apologized and has said that it will contact the customers concerned.
The broadband is often necessary to drill or modify the holes during the installation of cables in people’s homes – but sometimes this can go wrong.
“The guy who did the installation was incredibly sorry and it was a real accident,” explained Andrew Mabbitt, director of information security, studio Fidus the Security of the Information.
He said that the engineer then called his manager to arrange for the repair, but this never materialised.
“Received a phone call the next day from Virgin, saying that he would be in touch soon to arrange a date and they never called back,” Mr Mabbitt told the BBC.
He added that he also tried to contact the studio through its online chat service -but it was not working.
Another customer, Dom Valentine, complained that the company has left a large drill bit stuck in his wall for more than a week.
Mr. Valentine is a soldier of the British Army and said that the damage occurred in military housing.
“I was there when it happened,” he told the BBC.

He said the engineer drilled into a metal part inside of the wall, which caused the drill bit to get stuck. An attempt to remove it from the outside of the building did not go well.
“He was hit with a hammer, which has now broken the bricks on the other side,” said Mr. Valentino.
He added that he is still waiting to be addressed and, in the meantime, said he expected a substantial bill from the army, which owns the property.
Virgin Media has offered him £20 of credit, but he said the firm did not provide a repair.
“I was told the area manager would get back to me, that he has not” added Mr. Valentine.Garden cable
In another case, a Twitter user complained that a broadband cable has been installed obtrusively in his garden – in spite of the fact that he was not a Virgin Media customer.
Virgin Media has responded to these questions through social media, but some customers say the damage to their homes is still awaiting repair.
“Virgin Media apologises for any customer who has had problems when our services were installed at their property, as we do our best to make sure that the process is as smooth as possible,” the company said in a statement.
“We are now contacting the customers listed in this article so that we can see if the problem still exists and, if so, try to resolve the issue as soon as possible.”
The complaints have been left on social media relating to similar problems caused by other broadband companies.
