A billing error occurred on Monday morning when a batch process inadvertently charged some users twice. Although the issue was initially thought to be resolved by running a void batch, it was later discovered that a small group of users, specifically those with previously declined transactions being retried, were still affected by duplicate charges. The responsible party manually refunded these transactions and advised users to verify with their banks that only one charge was processed. If any duplicates remain, users are encouraged to contact support for assistance. An apology was extended for the inconvenience caused by the error.
