Plusnet continue to blame the customer
I fail to see how a router configured for dynamic DNS and IP and security protected (the passwords were not default and complex) can be responsible for the hijacking. Is it mere coincidence that Plusnet had put through a 'security' upgrade only a few days before? I would not like to think that this is another of those cover-ups so prevalent in modern services.
Either way, the reply (see below) I got from the supplier does not give me confidence and I will be certainly looking for an alternative in the near future.
From Plusnet customer support:
"Unfortunately we are unable to offer any sort of refund for this. The router is a third party router and as such we bear no responsibility for any vulnerabilities that result from using it.
If you wish to have one of our routers you can do so in one of the following ways:
Either paying for the router up front (£40) or agreeing to a new 12 month contract which would make the router free.
Either way there would be a £5.99 postage and packaging charge which would apply.
This is exactly the same as when you first took out the service.
I hope this resolves your query however you can respond to this message if you are still having issues."
