Product replacement or discontinuation is obviously quite usual - but that doesn't alter warranty obligations. The manufacturer should have stocked sufficient to meet likely needs. Without knowing the value. It is hard to know whether it is worth pursuing them; right now it sounds like they are ignoring you in the hope you just give up.

Are the contracts customer contract? Perhaps it may be useful to present the contracts based on the unexpired residue of the term left and whether or not the consent of the customer is required (for assignment). Are the contracts being assigned to a third party? Will the customer have to consent to the assignment?
If you are terminating the contract, you may need to look at the requirements under the term of the contract that will allow you to terminate without liability.
