Problem is, this is not my first purchase from them. Its my 3rd. In those previous orders they did not ask for that 6 digits code.
In their email, they stated that they have lost their previous order history when the new website is launched. I did send the proof of my previous purchase, and they still asked for that 6 digits authorization code.
And slyraven, they did explain what the code is in that email (you may see it in the screenshot). From this explanation, is it the same as OTP which usually entered by the credit card holder to authorize a transaction?
This is suppose to be entered by the credit card holder, not by the seller. There have been many cases where this OTP is used in credit card fraud.
