Condo turnover delayed multiple times, may chance ba for full refund?

Hello! Not sure if this is the right sub to post this, pero baka may naka-experience na magpa full refund dahil sa delayed condo turnover.

We purchased this condo way back 2022, tapos ang promised turnover date was September 2025. Pagdating ng September, naging December daw, then naging April 2026, tapos nung nag follow up kami ulit naging August 2026 na naman. Nakakainis kasi hindi man lang namin mapakinabangan yung unit, pero naghuhulog na kami and under bank financing na.

At this point gusto ko na sana magpa full refund kasi parang puro delays na lang. May naka-experience na ba nito? Ano ginawa niyo?
