They installed on Saturday and I called back on Monday night.
This is when I got the story about may or may not have found a fault so leave it for a few days. Will call them again tonight but I'm afraid they are going to make us wait an eternity until an engineer can come out again.
Not impressed. Even before it's working we've drafted a formal letter of complaint
Thanks.
Not sure about which models, but they are seperate modem (it's black!) and STB...
