The 28day warranty, and the fact it was refurbished, limits the liability of the seller though, too; it was cheaper and you don't expect the same lifespan.
once it is outside of the warranty period they may not pay for postage to return the product for repair, although they should pay for parts(&labor I'm not sure?),
that's the basis I've bought refurbed products from panasonic ebay store;
The refurbed aspects means it has lost some of the normal 2..5 year manufacturer obligation, and you'd expect a significant depreciation if they have to refund you.
15% sounds a good deal , for a refurbed product, but I'm surprised you've been tolerant of waiting 3 months for the repair/decision to be made, and haven't demanded resolution sooner, you've been able to live w/o it I guess.
I had been keeping in touch with them and the main response was due to covid-19 things have slowed down.
I did ask for an extension for my warranty once it was repaired due to not having seen the laptop in months but I received no response until this morning.
True, I've managed with out it due to using a playstation for the time being.
Regardless, I shall see what they come away with tomorrow.
