Q: Six months ago I bought a shredder from a local seller, which stopped functioning recently.

Since it was still under guarantee I returned it to the shop and asked to have it repaired. After the technician checked it, the seller contacted me and told me the seal was removed.

While I argued that I never touched the seal, the seller kept insisting it was opened. I had no reason to open the seal, as first of all I do not know how to repair such items and, secondly, the shredder was still under warranty.

After two weeks, I was informed that the shredder was repaired but there was a €12.50 charge. This is not fair, as it is not true that I tampered with the seal. What are my rights?

A: Since neither you nor the seller have tangible proof that the seal was broken before or after the shredder was purchased, it is your word against his.

If the seal was broken and the trader insists that the product was tampered with, then you may not be entitled to a free remedy.

If, on the other hand, you are sure that you did not touch the shredder’s seal to check what was wrong with it, you can insist to have the shredder repaired for free.

If you and the seller do not reach an amicable understanding, you may file a complaint with the Office for Consumer Affairs.
