Dundee Virgin Media customers were left without internet for days due to infrastructure issues.
The outage lasted from late Monday evening to just after midnight on Thursday morning and appeared to mainly affect those in the DD2 and DD5 postcodes.
Twitter was ablaze with angry customers, who were frustrated with the company’s time taken to resolve the issue.
Customer, Barry Thomson, said the company continuously changed the estimated time the problem would be fixed.
He said: “I stay in Dundee and chose to be with Virgin because it seemed to be the best.
“Anyway, for me at 1am on Monday morning, my internet turned off. I couldn’t connect to any sites so I contacted Virgin the following morning to be told that there was a problem but they had a technician already fixing the problem.
“I signed up to receive email updates and I called again on Monday night as the time they gave me wasn’t met.
“They kept the same email and status update and just changed the estimated time for it to be fixed, and, as of about 5.30am this morning I regained an internet connection again thankfully.
“I understand that things go wrong but you would think a company the size of Virgin would have a plan B in place. No apology directly to myself who had contacted them 7-8 times about it.”
Other customers also tweeted their frustration.
On Wednesday, Frazer Davidson tweeted: “Do I have to make an official complaint to get your service guarantee money back? Broadband down all day in the Dundee area.”
Another Twitter user, @anodynified, said: “24 hours to fix downed broadband across Dundee? Not impressed!”
A Virgin spokesperson said: “Virgin Media broadband services were restored to all affected customers on Thursday, following a reboot of the local internet-serving infrastructure.
“Virgin Media apologises for the inconvenience and thanks customers for their patience.”
Virgin added that the issue only affected certain parts of the Dundee network.
In October, the company revealed plans to roll out high-speed internet to 360,000 homes and businesses across Scotland by 2019.
The first phase, which will see 125,000 properties gain access to the network in Kilmarnock, Ayr, Prestwick, Dunfermline, Dalgety Bay and Inverkeithing, is set to be completed by the end of next year.
