Hydor warranty

[wreck]

5 weeks ago I had 2 hydor koralia 750's crap out on me they were 1 year old. I took them apart and found out that the magnets on both shafts were cracked and I could peel chunks off. I phone hydor cs and they say no prob will send out replacement shaft right away. And it has been 5 weeks and still nothing..... Anyone else have to wait forever for warranty from hydor? My tank is suffering...
