A:AnswerHey there!
To change the credit card used with your Geek Squad membership, you can either call Best Buy customer support at 1-888-BESTBUY or chat with a customer support representative online at the Best Buy website.
When you contact customer support, be sure to have your Geek Squad membership number and your new credit card information ready.
The customer support representative will be able to update your payment information and make sure that your Geek Squad membership is active.
I Hope this info helps!
