No collection and no refund after cancellation, despite many many attempts to resolve.

I ended my subscription in December. January my services ended. February I was billed a random amount. For aparently the 3 year old router I had. In cancellation no arrangement was made for its collection. Upon enquiry the router had to be returned and money to be refunded. I provided collection details, yet they sent a courier to the incorrect address. Ive asked numerous times over 2 weeks now for this to be resolved and absolutely zero feedback from admin, accounts, escalations nor from the priority support team.

Your services are a disgrace.
