You can update your name on your account by going to your Contact Info page (Settings > Contact Info) so that it matches the details on your payment method.
You may need to prepare documents as proof of your name-change, in case the system requests you to upload a document to verify your identity.
Thank you for the response.
I have already changed my name on the account, it is under riview at the moment and so far I haven't been asked to furnish any verifying document.
I just hope the whole process gets done fast as my productivity is being hampered
