I made a few transactions with this seller, awesome support, prompt and polite replies.
I am sure that whoever complains in the manner that OP did, is just a scammer or someone underage that doesn't know how any form of support works.
Gensen is really professional and i am sure even if he made any mistake, he would happily correct it without hesitation.

Also, Gen, thanks for all the smooth transactions, i am glad that there are people even thousands of km away from me that are able to honour even the smallest business deals and i can trust.
