Not all letters do come in post joysutty- not anymore- its an annoyance to me as they send me texts for 'portal appoinments' for both me and my 2 sons at home (21&17) as i deal with all their medical appts etc too- but it never says which person they're for at beginning, i have to click on them and then put in details & if its not my own, go through it all again, or again & again to get correct one, but also i was told when i rang up that IF you DON'T click on it they then send a letter out instead! So why not just send letter in first place! Yes these texts are worrying as then you can't sort them especially if its weekend, or after 5.30! But as for OP, yes I'd ring on monday- as its odd a 'young lad' answered, saying receptionist had 'gone home'?? It could just be kids messing or could be genuine but just a mix up, for example, there's more than one person with same name, as my son used to attend same childrens clinic when he was younger, as another child, same name, so its possible you got their txt by mistake? But if youre not expecting one from that dept definitely ring on monday- not that number, but the main hospital number,& ask for gastro dept? I think you CAN actually opt out of the text message service also? You could ask hospital when you ring?
