google photos ios app

i purchased a 10 TB google 1 plan via the 'google ios app' on my iphone about a year ago. i was charged $100/month.

a few months ago, i came across 'google 1 payment plans' + saw that the 10 TB was decreased to $50/month, after i had been playing $100/month for a year . when i contacted 'google 1', they said i had to check with apple for pricing since i had signed up on an 'ios app'. i then noted that the '10 TB plan' wasn't listed on the official google 1 website, but somehow i only saw that it was an option when i was using the google photos ios app. i never suspected that the platform i was purchasing on was charging me twice the rate for a service other people are paying $50 right now.

'google' basically told me that the only way to change the payment and "re sign up" the account via chrome browser was to contact apple support. what do i do from here?

🙏TIA🙏
