Many times there was a complete loss of signal, I had to submit a ticket, wait for someone to pick it up, ask me additional unnecessary questions, only to find out a day or two later OpenReach planned maintenance for that night and morning. It was irritating watching status page on Uno saying there are no issues and connection is fine while you have no connection at all, apparently as expected.
Uno always told me there is simply no way for me to find out when those maintenance windows were planned for.
After switching to another provider with a lower rate, I know it was not true. I can now see upcoming outages and past incidents recorded by OpenReach (even those I did not notice). Not a useless "always OK" status.
I don't use a landline, only broadband. Apparently, Uno could not possibly check the signal on their end (I paid for their phone line, btw). I had to buy a phone just so Uno can rule out problems with the phone line they provided.
My current ISP was surprised this was ever a problem to check for Uno.
Of course they charged this nasty disconnection fee. Plus since I submitted cancellation request to wrong dept, they also charged for extra few days.
