"Operation cancelled again"

Totally disgusted with this hospital. After waiting over 2 years for a Hartmanns reversal I was finally given a date of the 9th September. It was written all over my notes that if I was given a date it was not to be cancelled due to me being a single mum to a special needs child, and I would have to sort out respite care for my child. This was not an easy task for me to complete. Well all was sorted I fasted for 36 hours like they asked me to and then with an hour to go before I was due to be in hospital they phoned and cancelled my operation due to no beds. Totally disgusted with how I've been treated. Been told by managers they would rearrange my operation for next week and they would ring me by this afternoon to give me the date, well needless to say I have received no phone call
