"Lack of care"

My father, an elderly cancer patient was told a pharmacist would call him today but no one called. He called the practice in the late afternoon and was told “a pharmacist can’t call you today anymore as they’re too busy but they’ll definitely call you tomorrow”. He’s just had major surgery 2 weeks ago to remove his bladder, prostrate and lymph nodes due to an aggressive cancer and this is the care he receives from his GP…..total neglect
