Why have I received a debt collection letter ? I have not been a customer since june 2020. It can not be for unpaid usage as a payment was taken out in july as I forgot to cancel the direct debit. The router was left at the property when I moved as I was unsure what wires were for what and being a block of flats I did not want to cause any problems. Help me with this as I'm at work during office hours and I'm unable to call during this time.
