Known issues

Some users experience long wait times when contacting the wholesale operations desk, especially during peak hours or after major incidents. It is advisable to escalate issues to an account manager or follow up via email if delays occur. Additionally, out-of-hours support is limited, so urgent issues may not be resolved until the next business day. For emergencies, contact the operations team directly. To minimize wait times, consider calling during mid-morning or mid-afternoon when lines are less busy.
