* Phone: You'll need to find the specific phone number for the department you need to contact. Their website (which you should search for - "Wesleyan Assurance Society website") will list contact numbers for various services like claims, investments, etc.
* Website: Their website is the best place to start. Look for a "Contact Us" section which will likely offer various contact methods including email forms, online chat (possibly), and possibly postal addresses.
* Post: Again, you'll find the postal address on their website. This method is likely best for formal correspondence or sending documents.
Important Note: I cannot provide specific phone numbers or email addresses directly as this information changes frequently and providing outdated contact details would be unhelpful. Always use the official Wesleyan Assurance Society website to find the most up-to-date contact information.
