When one person is watching Netflix, every other device on the network is either disconnected or has to deal with slow speeds of around 0.5Mbps (or lower!) download making it impossible to do anything.
This is not just when someone is streaming either, slow speeds 90% of the time which is not acceptable for a service we're paying for monthly, especially considering we lose internet access for 1-2 weeks each month because you refuse to change the date we pay our bill and we don't get paid on that date anymore.
I'm sorry to hear that you're experiencing wifi issues and that the payment schedule on your account is causing problems.
Have you had the opportunity to run through our wifi troubleshooting guides here?
In terms of the payment date - you're right that we can't change this. It isn't necessarily a refusal to change the date, more that we simply don't have the facility to do so (yet). In the interim, you can make manual payments via debit card through either the member centre or one of my colleagues in the Customer Services team (0800 328 4620) up to 14 days after your payment date. Although you'll still get a reminder that the payment is due, this can be dismissed through any Windows based PC/laptop and you'll then be able to browse without interruption.
Let us know if there's anything else that you need.
