Known issues
Callers frequently experience long wait times, particularly during peak hours and tax season. To reduce wait times, try calling early in the morning or mid-week. Automated menus can be confusing, and reaching a human agent may require patience. Some users suggest pressing '0' or waiting without selecting options to speak to a representative. Additionally, support is limited if you do not have your National Insurance number or sufficient identification, so ensure these are ready before calling.
