I was advised three months ago that my father's account was closed and his estate would receive the final notice at the time of the usual billing. No such notice has arrived. My sister, the executor, has attempted to contact the Shaw employee she was advised to speak with but her phone messages and emails have gone unanswered. Staff at the seniors residence have been contacted by Shaw and were left with the impression that the account may not have been closed. How do we get confirmation and a final notice to know that the account is closed?
