Known issues
Customers frequently experience long wait times, especially during peak hours or after major incidents. Calling early or using email for non-urgent issues can help. Some users report difficulties in cancelling services, often requiring persistence and escalation to supervisors. Delays in engineer appointments are also noted, with follow-up calls sometimes necessary to expedite service. For unresolved issues, visiting the headquarters in person during business hours may be an option. Written confirmation is recommended for any escalated complaints or cancellations.
