ENBD Duo still giving 5% points on Education?

Hi All,

I've been using the ENBD Duo Mastercard Platinum for educational spends, usually done online. And I've been receiving 5% points on it up to the monthly points limit as well.

A recent transaction I made using the same education payment link was captured as "government services", MCC 9399, rather than as an educational spend. I realize this may be a change in the merchant category of the service provider and have reached out to them for clarity, but has anyone else had a similar experience lately?

Would appreciate your replies and insight.
