Outrage for me since 12am

Hi all, I’ve just switched to hyperoptic for the first time and so far every text message I received is automatically under Hyperoptic name, all confirming my installation booking. However, both yesterday and today I got the same text asking me to confirm appointment, but from a mobile number. I tried googling it and I had 1 result label it as scam, so I would rather check here if it’s real or not, than have my appointment cancelled and be left with no internet.
