I'm currently with Spark on an Unlimited UFB 100 plan plus Landline for $104.98 p/m (with the Free Fibre Speed Update Credit)

Received in the mail an offer of either 6 months or 12 months free Netflix, if I sign up to a 12 or 24 m contract. The problem is, I would be worst off as the new plan is $114.99 p/m, even with the Netflix credit. I'm already on Netflix however regardless of this, I would be paying more.

I'm keen to stay with Spark long term, what are my odds of getting the offer while retaining the 100 UFB speed discount? I don't like to haggle.
