Please stop sending Customer Feedback Surveys

[#1]

I get an email request after every contact with Plusnet.
I suspect somehow the spam I receive immediately afterwards is connected.
It is addressed to me by name, to a mailbox I only use for Plusnet.
Is it possible to stop sending me these surveys please.
I will not respond to them again.

Hi,
Sorry about these and I'm equally sorry that we can't really stop sending them!
There's a trigger on the number of tickets/calls that you make to us that cause one to be sent.  If you don't want to fill them in anymore, then please just ignore them,
I can absolutely state with authority that these surveys will have nothing to do with any subsequent spam that you receive.
