My 80 year old mom arrived there on Friday after having major heart surgery, she was delighted to be in this rehab after hearing so much about it.
On Sunday I phoned her in the morning to hear her answer her phone crying , she could barely tell me that she had asked for assistance to the bathroom, nurse lead her there and walked out only to hear my mom moan for help, mom fell to the ground flat on her face. Taken to hospital where she had stitches! Spent 5 days there.
Tonight she was transported back to rehab! Went looking for her clothes! Nurse knew nothing about her belongings! Found them in bags on a floor , she was extremely rude to me! Asked her for assistance in sitting my mom up only to grab her in s tought manor!
I will be making calls tomorrow to speak to person in charge. This is pathetic!
