Feeling Heartbroken Over My Father’s Situation

My father is quite elderly, and we recently discovered that he was tricked into making large payments that he didn’t fully understand. Unfortunately, he signed the documents, and now the charges keep coming from his card each month. The bank says there’s nothing they can do to stop it. It feels like they took advantage of his age, and honestly, I’m really upset. I’m reaching out to everyone I can, trying to find a way to cancel this, but it’s looking difficult. My family will have to adjust our budget and use our savings to cover these payments. I’m preparing myself for the worst if we can’t reverse this, and I’m feeling scared and sad. I want to turn to Allah for help. Can anyone suggest a dua I can make? Please keep my family in your prayers and give me some hope that things will improve. I have trust in Allah, but I’d really appreciate some support. Edit: I want to explain that I kept my original message vague because I mainly needed emotional support and to share with my brothers and sisters in Islam. I wanted reassurance to strengthen my connection to Allah SWT and to ask for prayers. I didn’t expect so much practical advice, and I’m grateful and moved by everyone’s concern! I’ve also sought professional advice elsewhere for legal and financial guidance specific to our country, and I’m planning to consult a lawyer soon. Still, every kind word and suggestion here means a lot to me, and I’m considering them all, even if some don’t apply directly. Thank you all so much for your help. I’ll look into everything carefully. May Allah SWT bless you all.
