everyone I know who has ordered from Necroharmonic has waited a minimum of three months to receive their goods - everything ranging from a CD to a t-shirt. and in all cases, they received no responses from the owner when inquiring about the status of their orders.
Evilmusic ordered a bulk order from them almost a decade ago; they were out of some of the order and promised to fill it later. Months went by, and then we noticed the product was available on their website. We then fired off an email to them asking for the rest of our order. After a unconscionably long delay, in which nothing happened, we posted a question to a forum asking if Necroharmonic was a ripoff. We got a reply the next day.
I am told their service has improved.
Everyone screws up sometimes, and so generally we do not make a big deal of things. Ours was not the only case however.
