Unfortunately, your case would take months and months, and TK would wait for you to give up. Don't give up.
In the first plan, they should have refunded your whole ticket. The agent was definitely wrong. If there is a schedule change for more than 15 minutes, you are eligible for a FULL REFUND. However, as the agent changed the date to 15 days later, this means that you have lost your right to cancel without penalties. You should have HUACA.
Unfortunately, TK does not run its own call center and sub-contract call center agents, they have referred you to communicate with a sales office.
Is the flight date past or not? If not e-mail or call a sales office ( if Spanish is your main language call Barcelona, Madrid, Mexico City, etc... ). If the flight date has passed and you haven't shown up, unfortunately, the only way to get your money back would be to take legal action.
Sorry, but we are all aware of how bad TK IT...
