My ISP has notified me that my Internet service package "will no longer be available" and that they will upgrade my service to a new package, at a higher price. When I signed up over 5 years ago, I signed a contract agreeing to a specific service at a specific price and I was locked-in for 24 months, lest I be charged a penalty for early breach of contract. I'm still using the same service although I am now free to leave without penalty.
Under EU consumer law (or Croatian law for that matter), can I demand that my original be grandfathered? Assume that I do not wish any change of service, and that I obviously do not wish to pay more for an upgrade I didn't ask for.
If possible, please provide relevant links or references.
