I cannot provide specific contact information, such as a customer care helpline number, for StashFin Loan. Information changes frequently, and I don't have access to real-time updates for all companies.

Here's how you can find the official and most up-to-date contact details:

• Official StashFin Website: Visit the official StashFin website. Look for a "Contact Us" or "Help" section. This is usually at the bottom of the homepage.
• StashFin App: If you are a StashFin customer, check within the StashFin mobile application. Contact information is often available in the app's settings or help/support section.

Please be cautious: Verify any contact information you find online through unofficial sources with the official StashFin website. This helps avoid scams.
