I wonder whether the DPO bounced that back into customer services, or it was a delayed CS response from your previous interactions.
You usually get a ticket number from the DPO team. They usually respond in days rather than hours. But if you can respond to the email that send you the link to the reset form, explain how from a customer point of view it doesn't fix the issue at hand.
