it's seems that I am not the only one who face this problem.
I am a careful person and I never buy online without checking the
sites owner, but this time I was in hurry and I ordered a software
from atompark.com ( Russiam company claiming to be from USA ), called
email hunter, it was  really a bad mistake, the software was very bad
and contain Trojan, I deleted the software from my PC  and contacted
Plimus from the first day to give a refund, it's about 110 dollars .
Plimus didn't react, they ignore me and the owner of the software is
Russian , he refused to give my money back, he write in his website,
30 days money back guarantee, but I didn't receive my money till now.
I faced similar problems with clickbank.com and 2checkout.com, they
gave me a refund from the first day, they are serious and they have
name, but Plimus, well you know it your self.
I like that all people follow my problem with Plimus, I will send them
a link of this thread and I like to see what's their answer .
I will update you as soon as I get a response.
