What the hell is happening?

What the hell is going on with 3?
I started using a 3 mobile dongle some years ago and it was brilliant, both at home and on the move. Now though, a few years down the line, I just use it at home and it is absolutely appalling. I have found that the only time I can get online with few problems is between midnight and 3pm, not very good if you're asleep or out during the day! Between 3pm and midnight is an absolute nightmare, never had this problem in the first few years.

What is there to like about 3? At the moment, nothing!
Time to ditch 3? Maybe, if things don't improve very soon!
Would I recommend 3 to a friend? At the moment, no!
