Read the terms of the agreement, you cannot back out of it. However, you are also completely wrong in your calculations, Black Knight, and you are still making a pretty good saving.
22 X 13 = 286 + 125 = 411
so your actually paying £411 for a £500 bike and you had 13 months interest free credit ???
dont know what your moaning at
This!
They can't say what the final payment will be (Norm will be along to repeat that in a bit

- see I have listened Norm!).
Congratulations.

Let's see if we can help bring Black Knight up to the same level of understanding.
Pretty pised off with the whole thing tbh. The saving is negligible through C2W. With the new changes i'll actually be paying a premium of 20% over list price.
Wrong. You are saving around 20% and getting an interest free loan for the rental period.
Yes £500 voucher
13 payments of £35ish quid (gross)
I've highlighted the important bit which you are missing, BK. £35 gross is probably £22 a month (depending on personal tax circumstances) so you are only paying £411.
Alternatively, just don't buy the bike at the end of the agreement.
The final payment situation is ridiculous. The bike will either going back this week under a cancellation or ill leave it out to get stolen.
Aside from this being gross misconduct (do you really want to lose your job over it), sit back and look at the real facts of the scheme, rather than your misunderstandings.
Also, if the bike gets stolen, you will be required to pay the total new price of the bike to your employers, now that
is a way to lose money and it would be a shame to do that just because you don't understand things.
