Wait wait wait...
There is a lot here to look at and intially... did the store owner when selling the fish ask if the tank was matured?
Did they say when you bought the fish saying "You have a 7 day life stock gurantee, as long as there is no ammonia or nitrite present".
I imagine they didn't say any of that.
Whether or not the tank did have trace amounts of ammonia/nitrite the refund should still be issued. It's amazing how Maiden Head aquatics have simply placed the blame on a possible Ammonia/Nitrite issue, why couldn't it be anything else... stress, disease or illnesses? How is it possible to come to such a fast conclusion?
Amazing, truly amazing how people can do that. Refund should of been issued and still should be, whether or not the customer was rude or anything along those lines there is no reason the manager should be able to turn around and go back on his guarantee.
P.S
If the fish died in the tank, then he did a water test. Is it inconceivable that the spike was caused by a dead fish being in the tank? Perhaps this could of contributed greatly to the water stats assuming the test kits were correct. After all we know how bad snails are for when they die?
Too many issues if maiden head are going to act like this and point the blame on it every time they may as well never have a useless guarantee on live stock. I had a lot of respect for Maidenhead aquatics though if this is how they treat their customers.
they should replace the fish....
how ever, have u been rude to them first?
I don't think whether you're rude or not should effect your rights to a full refund.
