A company won't delete my data

Step-by-step legal guidance hasn't been verified in Ελληνικά yet, so it's shown in English below. The interface is in Ελληνικά.

Have you already formally asked the company to delete your data?
Yes, I asked
Did they respond within one month?
They refused, citing a legal exception

Article 17(3) lists when a refusal can be lawful: freedom of expression and information; a legal obligation to keep the data (e.g. tax or accounting rules); public-interest tasks; public health; archiving, research or statistics; and establishing, exercising or defending legal claims.

Compare the company's stated reason against that list. If it clearly doesn't fit any of these, you can complain to your Data Protection Authority. If you're not sure whether the exception genuinely applies to your case, that is exactly the question for your DPA or a lawyer — this portal won't guess it for you.
