Unable to confirm Email address as part of new contract.

Dear Team.

As part of my request for a new mobile phone contract, I received an email from du asking me to confirm my email account so that they can send me further details through my email. But unfortunately when i am trying to verify using the link provided by O2 team it is throwing me an error saying “The e-mail address is not assigned to this customer account. Please log out and then log in with the correct customer account.”

Please find the below screenshot for your reference.

 

Looking forward to your inputs.

Regards
June Mohan
