Crap quality , not always returnable and no way to leave reviews

I keep trying to order stuff because theres some cool looking stuff and have spent a bit of money ...but Im done . Ive returned over half of what I ordered due to bad quality . But still waiting on refunds . And the last product is unreturnable .
I looked for a way to leave a comment but the button doesnt work and no way to reach Opensky or the seller .
Worse thing is unable to leave a product review to warn others and hold the seller accountable somewhat .
