Dear customer,
Sorry for the inconvenience and appreciate it:
1. Normally, this issue could be fixed by--- spraying isopropyl alcohol or an electronic degreaser or Peavey Funk Out Electronics Cleaner Spray or a Tuner cleaner
Then blow the scroll wheel with a dryer or high-pressure spray gun etc.
2. If still fails, kindly take a video of how the scroll wheel worked weirdly for our reference, it is just for internal verification.
3. Kindly share your order ID (the screenshot of purchase page would be great)for our reference too.
4. Kindly confirm your current shipping address + personal contact.
as we might have to escalate your case to sales for further assistance. You can share it with us via the online chat in the APP or by sending it to our email, service@sofabaton.com. Thank you
