Argos - sells replacement cover for items under £150
(this replacement cover includes accidental damage)
if the paperwork you get is accidentally damaged and needs to be thrown out
Argos "can't prove your not scamming them" (because they don't bother keeping long term records of ACTIVE insurances in this range) so they treat you as if you are scamming them.
By treating the insurance cover you paid for as invalid because the hard copy you were provided with is destroyed.
I called their customer support and was told, "Even if you provide us with a bank statement proving you purchased the product and insurance from us - unless we see the original plan (of which we don't provide replacement copies of) we can't prove you haven't used it yet. So your product would not be covered."
I asked if this was stipulated anywhere, "yes".
Here it is, "Taking out Argos Replacement Product Care really is a low cost way of making sure your every-day electrical items are looked after. To get a replacement, just pop in to your local Argos store with the broken item *and your plan details.*"
