Can you help me with my Fc akk (03614805533872128)

Can you help me with my Fc akk (03614805533872128) When linking my account to my E-c account, I confirmed the linking via email and was prompted to say that my refund was too low to link. Then, when I tried to change my age, I accidentally logged out. Can you confirm my previous request so I can log in to my account?
