Telus can't tell me why they cancelled my account

Today, my wi-fi went out inexplicably and when I logged in to my account, I found that my account had been cancelled. 

Without notice.
Without consent. 

I spoke to THREE representatives - none of them could tell me WHY it had been cancelled. There was no reason given, and no documentation on file. I was told that my account would be re-instated and my service "re-ordered" - and then told it would take 24 hours to complete. 

So, I am now 24 hours without internet access thanks to something that THEY did, for no reason.
