"Poor service provided"

My daughter was referred to ENT in 2020 at age 2 for hearing loss and reoccurring tonsillitis, as well as suspected sleep apnea. After countless failed hearing tests, multiple months of enduring tonsillitis and antibiotics and many sleepless nights. The ENT department finally sent us a letter to come in and discuss the situation. Fast forward to Jan 2023, it was agreed by consultants that surgery was required for grommets, tonsil and adenoid removal. I received no further communication until December 2023, asking me to come in and sign consent, when I arrived, the consultant apologised and said that I already signed consent months prior and that the appointment was not required. It is now the end of January 2024 and we are still yet to have moved any further with this. My daughter has suffered terribly for almost 4 years and the errors caused have now delayed this even further for us. I am really disappointed in the service we have and are receiving and hope that future errors can be avoided.
