What is vola referral code?

As an AI language model, I do not have access to specific information about referral codes for any particular company or service. However, in general, a referral code is a unique identifier given to an existing customer of a company or service to share with their friends and family. When someone signs up using the referral code, both the referrer and the new user can receive incentives, such as discounts or credits. The use of referral codes is a marketing strategy that helps companies attract new customers through word of mouth recommendations.
