Thanks to @Rach_H, Townman and other members of Plusnet staff who tried to assist me with this reward card not received issue. Unfortunately, nothing came of it until I logged an official complaint, then I was contacted by the team, and told initially that it was now outside of the timeframe so I wouldn't receive a reward card.
This was disappointing as it was a relevant factor to me choosing to go with Plusnet in the first place, I was asked whether I had signed-up directly on the Plusnet website, which I had after following a link from the MSE site. I was then told that the link hadn't worked and that there was a fault with the Plusnet website.
Eventually, on a further call I was informed that the MSE website should have issued the reward card, I said that this didn't sound right and was suspect, I was then told that a payment in the form of a cheque would be sent out, which it was, thank you!
Much hassle, persistence and inconvenience on my part for something that should have just automatically have 'worked'!
