How can I change the credit card info on a client's Shopify store?

[Tsagheer2_]

Hello Team,

I've created a shopify store for my client a month back with 1$ subscription where I've placed my card. But now after delivering store they are unable to change card. Plus they used app name Globo product variants which they installed and deleted after that but the billing cycle is adding subscription charges of that app too. Now the client isn't responding and my card is being deducted by the 100$ payment without any concern. Is there any way to remove my card first or remove that 99$ dollar billing sickness!

Thank you
