Shopify upselling offer of subscription plans

I had an issue with my subs bill.

I was on a monthly plan, then I changed to an annual basic plan so I had an offer of 233$ instead 257$

The problem that Shopify take money 2 times from my card!

I chatted with the support team and they told me there’s no upselling offer in shopify! I don’t have a screenshot that provide that offer!

I asked for a refunding the selected bill but they told me no it’s already deducted from the new bill!! but this is not right , so please if you have a screenshot or any solutions!!!
