Physically and mentally devastated after four dates for knee replacement op cancelled at last minute

A Magherafelt woman says she's physically and mentally devastated after getting five dates for a knee replacement operation - four of them cancelled at the last minute. Heather, who is 55 years old, is in constant pain and agreed to accept a cancellation date if one became available in order to get the operation done earlier. However, she says she had no idea that by doing this it would delay rather than speed up her journey to the operating table. She spoke to our reporter, Nicola Weir.
