i brought mix sarra seeds from best carnivorous plants .net this march.

but none sprout even after stratification for 5 weeks. don't respond to GA3[500ppm and 250ppm] for 24hrs.

i might have left it out of the refrigerator for 4-5 days but could this affect viability ?

No.

How long has it been since taking them out of stratification?
After stratification, they take 1-4 months to sprout.

today i saw they were pitch black - somehow - and dead supposedly

That sounds like some sort of mold got them.
How damp were they kept?

100% humidity in a closed container with moist sphagnum

1.5 months

%100 humidity does not sound good.
Mine are in $50 at most.

how best to germinate sarr seeds Daniel ?

I, personally, mix in the seeds with finely chopped LFS. I can't chop my LFS, so I roll it between my fingers.
I then wet the mixture, and wring it out, to remove excess water. I then put the LFS/Seed mixture in a snack bag, label it, and put it in the refrigerator for 4 weeks. After this time is up, evenly distribute the LFS/Seed mix on top of a pot of moistened CP mix. Put the pots where you have sowed the seeds into 1 gallon plastic bags, to keep the humidity at about 75%. After a few weeks to 4 months, the seeds will begin to split, and the plants will sprout. After the plants have 2 true leaves, slowly lower the humidity over the course of 1 month, until it is at an acceptable level for adult plants. Then, care for them as you would care for adult plants EXCEPT you should skip dormancy for the first 2 years, to get plants that mature faster. After they begin to produce adult pitchers (in 2-3 years), begin to give them dormancy.

I use the same method of stratification as Bananaman, but for 5 weeks instead of 4. After that, i sprinkle the seed and Sphagnum onto a pot of moist/wet peat, and stick them in my greenhouse.
I noticed germination in 3 weeks.

With that method i managed to germinate year old seeds which spent a winter of -16C on an unheated greenhouse shelf.

sarr. seeds r pretty tough then, isn't it ?

anybody used GA3 hormone to break dormancy and what strength ?
