Hi Martin,
Thanks for taking the time to get in touch with us, I'm really sorry to hear you're not getting the best from your 100Mb service =(
As one of our flagship services it's sad to you're not seeing it at it's finest, so hopefully moving forward that will change. I've had a look at several different potential issues with your connection, running many tests to ensure no stone is unturned on a first line level.
With you mentioning a potential UBR issue this is something I checked first and it seems your network is absolutely perfect. There are no known issues in your area, with the UBR looking in tip top condition. I've also monitored your connection for any power issues, noise on the network, and any error messages. These checks have also shown everything working in perfect order.
This doesn't mean the issues you're facing are phantom related, it just means that I've checked everything I possibly can. Moving forward I'd recommend speaking with our technical support team about the troubles you're having, that way they can run some in depth online tests. You will need to be sat at your PC/Laptop for this, but they are available 24 hours a day, 7 days a week and it's all free on 150 from your home phone.
I'm really sorry I can't offer you anything more at this time, if you're still stuck for help after speaking with our support please let me know. I'm confident you won't need me, however I think it's always good to leave the door open just in case.
Thanks again for getting in touch.
Kind Regards
