It's a shame we're only on Monday as, when I had reason to call Customer Services a few weeks ago, I called on a Sunday morning and virtually got straight through. Maybe a few minutes wait at most, but if felt as though it was pretty much straight through anyway.
But it would be good if you could get them to hold fire for now but maybe contact you again in the New Year to re-arrange an appointment. Like I say, it is worth it if there are no extra charges involved, either for the installation or any changes to your monthly bill. In fact, my monthly bill has actually gone down as I was able to renew my phone plan at a lower price. But that won't be relevant here if you no longer have your landline anyway.
