Shaw Communications

I had Shaw for approx 1 wk. And I was not satisfied so I switched over to Telus. When I switched I contacted Shaw and told them I was not happy and that I was taking my services else's where. I didn't use any service the wk I was a customer and I returned their modem and devices at the store in Guildford mall in Surrey and appearantly the agent didn't not do their job properly cause they never noted my account I returned the items and now I'm being harnessed for a $1000 + on a outstanding bill and I refuse to pay it. I will pay a wks of none usage but not $1000
