"Phoned to try and contact my sister on Firth 2"

I'm  not impressed today, phoned to try and contact my sister who's a patient on this ward and was told that the phone wasn't around and could I phone later on, when I phoned later the person stated that the phone was still missing even though the ward isn't that big and they could have easily asked the nurse  to find out which patient had the relevant phone.

I asked why I wasn't allowed to speak to my sister as the member of staff wasn't helpful at all who was covering the desk this morning as well as afternoon. This is the second time this has happened and I explained that I was going to make a complaint as my sister had a fall the previous night and was really upset when I arrived and I'm also her next of kin, so to be told that I can't talk to my sister to check if she's ok or not, or needs me to visit, then its a clear breach of care with the staff.

It seems like they can't be bothered to check which bay has the phone or which member of staff took it as its supposed to be used for everyone to communicate with their relatives yet the phone is missing - but when I phoned that number is was a message stating this number isn't recognised so why say one thing when it can clearly be proved false. Its not very good to tell relatives things that are clearly untrue when they must have phoned that number first and checked for themselves, I don't think this was a mistake, I believe this person is lying. I'm going to make a complaint as this is the second time its happened already and I took it  to the ward sister as well as the ward manager the first time.
