Subscription Purchase product issue

Hello Developer support, In one of our live application we have seen that users are purchasing weekly subscription and automatically they shifted to yearly product. Due to this we have received high revenue and also refunds afterwards. To prevent this we removed our yearly product from the sale. In App Store Connect we have seen activations for weekly product and convert to standard prices are yearly products. Also we have seen weird behavior of user getting trial for same product for three times. For developer support people I am sharing my app id - 1320373866 , and here is the video of our issue - https://drive.google.com/file/d/1DBHw8ivgql4eNoo8NC3xo5v4wgr8Oh7x/view?usp=sharing , Also attaching trial behavior screenshot.
