AIBU over lack of contact

[Polkadotties]

My DM had an operation yesterday. Early this morning she text our family whatsapp group to say she can come home today. I was at the hospital yesterday, there's hardly any phone signal in the ward but if you walk just down the corridor you get signal.
My DF left at lunch time to get DM. His last text to the group chat was just gone 12 saying he was leaving soon. DM text at 12.55 asking what the weather is like as she hasn't seen daylight since Tuesday.
Since then my Dsis and I didn't hear anything, until about 6pm when I got through to the ward.
DF breezily informed me they are waiting for antibiotics.
My DSis and I have had our very elderly granny on the phone crying because she hasn't had any news and she is worried.
I had a bit of a go to DF on the phone saying he could have just walked down the corridor and got to some signal to send a text.
6 hours we didn't hear a single thing! My Dsis and I have been worried in case something has happened. DF didn't even tell us he had got to the hospital.
I've just had a message from DM saying I've caused stress by being abusive down the phone, something DF has probably greatly exaggerated.
AIBU?

To add, if it was me and my OH in hospital or my DSis and her boyfriend and my DPs weren't informed for 6 hours my dad would be going mental!

I fell down the stairs when I was 32 weeks pregnant, I called an ambulance and was monitored in hospital for about 4 hours. No damage just some cuts.

My mum gave me a bollocking when I got home because I didn't update her. To be fair, informing people was not a priority for me, I was more concerned about the situation at hand, and she upset me.Telling people off at these times is not productive, you could just say "you gave us a fright because we didn't hear anything, but how's everything going now?" Might be better at these sorts of times.

It's 6 hours, how did you cope before mobile phones?

YABU. Were you expecting real time updates???!!!

Yes yabu . Your df probably thought you would be aware that when someone is discharged from hospital there is always a massive wait for pharmacy and paperwork. A mild 'well you could of let us know'. Would have been suffice tbh.

I'm sure he'd have let you know if something bad had happened! Good for your dad for making your mum a priority rather than playing 24 news correspondent.

Bad news travels very fast. Waiting for pharmacy and discharge is very normal but tedious. DF was probably distracted, you and your DSIS could have distracted DGM.

Another YABU. They have nothing to report.

Six hours is really nothing. They were at the hospital. You knew where they were.

It appears IABU. Thank you for your points of view. The last week has been very stressful and I think it's all bubbled over
