I found my missing icp at this address（https://dashboard.internetcomputer.org/account/a721a85c2ec1f01003022d2d1bba09c70474eb5b07dd4f45012edc21e587371f） , then I called notify_top_up and it shows the following error,
how should I get back this 30 icp, thanks
@jennifertran can you help me ser?
I use the notify_top_up function of rkp4c-7iaaaa-aaaaa-aaaca-cai for recharging
it seems that you did not set the (correct) memo so the transfer is recognized as a topup.
Error:

There seems to be a refund_icp method but its not exposed for external use, so i’m afraid your funds are stuck at this moment
let code = code.unwrap_or_default();
print(format!("{} failed with code {}: {:?}", msg, code, err))
}
}

Your analysis is very correct, so is there any way I can get a refund? Thank you for your time.
There is no exposed call on the cycles minting canister to trigger a transfer, but it would make sense to add such a call to the CMC imo. Other question, are you the controller of the canister you wanted to top up?
yes， i am the controller of the canister
Ok, for now there isnt anything that can be done, i requested adding some functionality to the CMC canister Extend cycles minting canister functionality . But for next time I would suggest using something like https://www.icptopup.com/ which makes it a lot easier to top up canisters
