Backstory: In January of this year, I ordered an article from a webshop in the Netherlands (EU) which has an IP67 certification and for which usage under water is promoted. This product has been received but after usage in watery conditions, defects in the product appeared and in April, I contacted the webshop asking for a return; including pictures of the damages incurred.
Since this was a hectic period I completely forgot to return the device until I came across it again this week. So knowing that, by EU law, there exists a 2 year guarantee on products, I sent a mail asking if it was okay to retour the product via the original code or whether a new code would have to be used.
The response I got to this was: The article has been purchased on 31st of January and we informed you on the 18th of April that you were allowed to send the article for consideration. You failed to send the article and can't apply for warranty 7 months after the fact.
We have done all we need to, allowing you to retour the article. And won't respond to further correspondence.
Now, my question in this matter is whether they are right in claiming that they need not consider my request because they have already complied with their lawful requirements by allowing me to send said product for retour. Or whether they have an obligation to still consider this issue.
In short: What are my rights in this situation?
The product is an electronic device with a 10-year manufacturer's guarantee, so any defect can almost certainly be considered unreasonable within the 2 year period.
