how can i get my money in my octopus card?

For On-Loan Octopus (both Standard and Personalized Octopus), you can go to any MTR Customer Service Centre to apply for a refund of your remaining value. If the remaining value is less than HK$500, you will receive an on-the-spot refund of your HK$50 deposit (applicable to Standard On-Loan Octopus only) and the remaining value, if any. If you want to refund the remaining value in Sold Octopus, you need to call 2266 2222 for assistance, your Octopus will be checked at the office.
