Follow-up comment left accidentally

[waterparkpens]

I hit my return key by accident when leaving my feedback and also when I was in the middle of leaving my follow-up comment. Is there any possible way to amend either the feedback or follow-up comment or both of them?

You can try to call ebay about this but I think you might be sunk. After feedback for a transaction is left, a buyer and seller may respond to it each only once. 

As an aside, can I ask: were you on a mobile device when you left the first feedback by chance?

You can add a Response to your feedback indefinitely.
