Two months of intermittent service followed by twelve days with no internet connection at all. After several unanswered emails and numerous calls (each of them spending long time on hold before I could talk to anyone), they have been giving different reasons for the slowness/lack of connection - but never got to the bottom of it.
A BT engineer finally came to fix the line 10 days after reporting the fault, but he happened to be ill-tempered and verbally abused the caretaker in the building where I live, so he was not allowed in the premises.
All Onestream decided to do, rather than defending my interests (at the end of the day I am their customer and I am not getting the service I am paying for), was to say that I have to pay a £120 fee for a "missed appointment", when the engineer did not even ring my bell!!!
I think that Openreach may be responsible for the root of most of my issues, but Onestream have never offered the minimum acceptable level of support, despite I have done my best to be understanding and reasonable as a customer.
Conclusion: my honest advice is to avoid at all costs, unless you are after no weekend or evening support, endless response times and general carelessness about their customer's interests.
