I agree, return them and do a fishless cycle, especially since you have so sensitive fish - to be honest id be surprised if any were left soon. And you can do a fishless cycle for as long as you want, to build up as much bacteria as you can - for instance if you are going to have messy fish then you could make sure your filter is ticking over lots and lots of ammonia in 12 hours. My tank is 60 litres and it took just over a month to do 5ppm ammonia with no seeded media, but I got it up to 8ppm before I got fish, just to be sure. Plus you are going to spend a fortune in water dechlorinator if you do a fish-in-cycle. Oh and you can get a larger amount of fish to start with at the end of the cycle, because the bacteria will be there and waiting.
EDIT: oh and I've seen the filter system in P@H, it was out for some reason, it looks like theyrre all run off the same filter, so you best make sure if you do decide to get mature media from them.
*keels over* So... if I do return the fish, what then - do I literally just empty the tank and start again? I have four live plants in there! I'm sorry for coming over completely clueless, I read four different books (One by RSPCA) and the cycling business is not stressed at all!!

They just repeat what theyre told, they often dont have fish of their own. Get them to take the fish , no matter if they dont give you a refund, you will spend a fortune on dechlorinator having to do such big water changes every day if you keep them.
Oh but in case you missunderstood that last comment - you do still need to dechlorinate water for your fishless cycle, as chlorine will kill the good bacteria. Hopefully you already have some built up and your fishless cycle wont take too long.
Its the best way to do it - ill fish are a nightmare.
EDIT: remember to put the ammonia in less than 24 hours after your fish have gone, otherwise youll starve your bacteria. so get some ammonia now. If you cant get it in your local boots, order it from boots online. It is important you get the right ammonia because some other brands have additives and this can poison the tank. Boots one is fine, used it myself.
