Pathetic Service

I sent an email 8 days ago, ( Ticket no 372366), but no one has bothered to respond to me, instead I received a call asking me about the payment....what payment because I'm no longer connected. I've informed you that I moved and cancelled the connection, my email was acknowledged and collection of the router was scheduled but nothing happened, instead you're sending me invoices. I'm sick and tired of your bad service, that's why I don't want to continue with your service at my new place.
