Hi, Bro
Its Jason Yes,
They have wiped 1 of my own account credits I contacted the guy from which I bought those Educate FY credits were obtained from Kern Community Colleges but now recently AWS has blacklisted those colleges for some other reason and make earlier credits wiped but according to him only Educate FY codes are obtained from kccd Educate program but other codes are from event participation. Now as far as I know all educate Series codes are poisonous however I am not sure as john told yesterday that he has 12 accounts his 11 accounts are working fine but 1 of account credits are wiped but he had used same codes to all of his account until then never buy Educate FY Series codes from anyone also I have 4 of AWS account almost all of them uses same codes but they wiped the codes from one of my own AWS account but I was using VCC in that.

also you set your credit card limit to lowest and contact them regarding wiping of the codes as those all codes  ( except Educate FY ) codes are from legit events they may think that you have purchased those codes so try to convenience them regarding restore of the codes they can  waive your bill as those other codes are 100% legit.
