Helderberg hospital,,,,,no thank you

My wife went in 10 days ago, she has COPD and was not feeling well, battling to breath. After 4 to 5 days being there she said she's feeling a little better. The following day when I got there for visiting she was so drugged up, couldn't speak or open her eyes. I demanded to see what they had given and discovered that they had dosed her with sleeping tablets and morphyn.I just lost it. The following morning I called the doctor ( Dr Smith ) who told me that I caught her just at the wrong time, she was in that state because they gave her insulin for her sugar and it went way to low, reading was 1. Yesterday couldn't get hold of anyone not even the hospitals emergency number did they anwer. So we went to the hospital to see what was going on,. After big argument with security as they wouldn't let us in, when we eventually got to the ward, only to find my wife tied to the bed with a sheet as she wanted to get off to try and use the toilet. According to the staff they did that because they didn't want her to fall. Wife was going crazy so I untied the sheet and explained to the head nurse on duty that she has clostraphobia and has a history of it, cannot be held down or confined to tight spaces. One of the African nurses did not even know what clostraphobia was. According to the 3 stuge nurses that was on duty, they have the right to tie someone down I they think they may injure themself, why not get a Doctor or someone that knows more than these, I would go as far as say incompatant staff members. I will be moving her to another facility
