Multiple Account glitch

[Alreido]

Its been a month since I'm facing this issue ,  I am unable to verify my Stake account as it keeps rejecting my verification saying that I have multiple accounts , but I have only one account (that I'm aware of ). I have tried to contact the support team multiple times but they also don't have a definite answer to this problem . They are not even telling me how to fix this . I don't know what to do next , if someone knows anything about this it will be appreciated
