Frequently asked questions
Should I call or email about an incorrect bill?
Email is usually better because you can attach the evidence and preserve the exact wording.
Do I need to know the regulation behind the error?
No. A clear factual explanation and the right evidence usually matter more.
What if the supplier keeps saying the bill is correct without explanation?
Ask for a line-by-line explanation and then move to the formal complaint route if they still avoid the actual issue.
