TalkTalk, I really would avoid them and they are the most complained about provider.
Router failed. I need internet for work. They kept promising next day delivery, it took 4 days in total - even longer than they originally said:
Lied that they sent it out and weren’t able to track it. Found out from Yodel tehy hadn’t sent it for 2 days. I lost 50% of my data, used petrol to get into an office every single day, missed a job interview.
They said they would send £50 compensation. I just think it’s a joke.
