Can I claim compensation for mental harassment caused by a company's poor service?

Yes, Consumer Commissions do have the power to award compensation for mental agony and harassment, in addition to the direct financial loss or refund, where the facts genuinely support it — this isn't automatic, but is assessed based on the specific conduct of the company and the impact on you.

To support such a claim, it helps to document the pattern of poor conduct clearly — dates of complaints raised, how they were (or weren't) responded to, the number of times you had to follow up, and any specific impact this had on you (time lost, stress, disruption to plans, etc.).

The amount awarded for mental agony varies considerably depending on the commission's assessment of the specific facts, and tends to be more meaningful in cases involving prolonged, clearly unreasonable conduct by the company, rather than a single, isolated service failure. Presenting a clear, well-documented timeline of the harassment will help your lawyer make the strongest possible case for this specific component of compensation.
