Bad service

2019 I purchased a 50lt logik urn(Game benoni Lakeside) which did not live past its guarantee. Guarantee given was 3yr and in 2021 had to return it and was given a new one as replacement which also could not reach its given Guarantee (3years)...Today had my husband return the it and we where not interested in getting another urn because it Cleary does not last very long.Was aware that probably cash refund was not gonna be possible hence we requested on a voucher so that we buy something else. We where told that because we didn't have a box therefore they can not be able to give a voucher but another urn replacement. To my surprise the guarantee years on the same urn has been reduced to 1year which to me clearly states that you guys have seen that your product does not last very long. This is like *****ing from your customers. This only works a year and to get to two years it's buy chance then you guys won't be replacing since the years have been reduced. I need this fixed, I would gladly accept a voucher that taking something which I certainly know won't go a long way. I mean this would be the 3urn.. I will await you response in regard to this as I'm certainly not happy with how this has been handled and the lame excuse of a box I'm definitely not taking it! Who keeps boxes of all the things they purchase, try another tactic coz this one definitely isn't working.. Proof of purchase and booklet inside was provided and that's proof enough that this was brought from you. Store in question is game benoni Lakeside... All purchases and returns where done there.
