Why doesnt telus offer plans for old citizens that might have problems managing their finances. Racking debt and interest on late payments should not be the modus of operation for a telecom company. There should be guards in place to ensure that someone with dementia or alzheimers does not need to risk their financial well being and still have a phone line.
I suggest power of attorney in this case. We had to do this for my grandmother, this is a family or caretakers responsibility. There is no way for any company to collect this information or act on a clients behalf.
