May you kindly advise as to why an amount of R3300 was credited into my account?

Good day Hollard , On the 13/01/2023 I received a payment from Hollard and I'm not quite sure what it's for. I sent an email to enquire however I haven't received feedback, the payment was R3300 and couple of cents. May you kindly advise as to why an amount of R3300 was credited into my account?
