You can get pretty well any ISP to give you a discounted price. It's called a "Retention Discount" or "Loyalty Bonus" or similar. Several also have referral schemes, whereby as a result of someone introducing a new customer both receive a benefit.
Many even have specific Retention Departments for the purpose. It just needs customers to be aware of this sort of thing, as they are increasingly becoming. Not just in the field of broadband either.
Your style does very much suggest a hidden agenda, which has to make one suspect you expect to benefit. Alternatively, building on someone else's comment in another forum, you are naive and have only just discovered this.
The only puzzling bit is your deadline date. Maybe it is a referral scheme of some sort.
