Breaking out of fixed term deposit account?

I signed up with KBC under their interest upfront 12 month deposit in October 2012. I was paid interest as agreed and I had no problems with the process. I recently saw a house that I would like to use these savings as a good equity base for. I then enquired about releasing the funds with the offer of full interest refund to KBC, as I proposed breaking my end of the agreement. I was told 'thanks but no thanks' and to wait until October 2013? Can I go anywhere with this if I keep pushing them?

Contact KBC and ask the breakage fee.

The breakage fee varies from product to product.

KBC do mention the possibility of breakage, at their discretion, in the T&C's for this product.

The 'at their discretion' bit seems to be the problem, I have applied in writing and was told through the deposits team (after a management consultation) that it was not a runner. I went to T&C's as well before this, thinking it would be possible after a partial or 100% interest repayment. I understand they owe me nothing but I would have given them my cash for 6 months gratis!

Try and escalate the issue with KBC.

The T&C's talk about "exceptional" circumstances. You need to be giving a good reason as to why you want the cash early.

I tried again in writing citing 'personal circumstances'. There is no option for breaking out of interest upfront account with KBC even after full refund of interest (at about 3.6%) is offered. I appear to be running out of options.
