The weekend doesn’t count as working days , so it’s 3 days really , the target repair is 2 days so you should be eligible for a day compensation, that’s assuming it’s fixed Monday, there is always the chance it’s repaired before then (or unfortunately later than that ) ….obviously it can be stressful without service , but this is a service that costs around £1-£1.50 a day assuming broadband is also taken , more like .75p a day for a standalone phone , strange that something apparently so essential is so cheap
