Hello Gavinda_Harsha,
Welcome to the community!
Sorry to hear your account has been suspended. It can happen if the system suspects activity might be fraudulent. Fraudulent behaviour tends to include multiple access attempts to a particular line or account. While it's true that making multiple changes to an account can be for legitimate reasons, they cannot overlook the possibility that nefarious actors may have access to a customer's information.
I understand you were just trying to ensure your address was correct. however, your repeated sign-off and sign-in's following your purchase could have been viewed as suspicious and triggered the suspension. My account was recently suspended as well. Apparently, my VPN triggered the suspension. The IP address was considered suspcious and my access suspended. The system isn't perfect, but I'm glad there are measures in place meant to prevent fraud.
You would need to contact customer service to have them remove the suspension. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above. Once in contact with them, they will likely refer you to their Fraud department and/or Verification/Validation team in order to get it sorted.
Hope this helps 😀
Cheers
