This typically results in mail from very infrequent senders (such as our support address) being spam-foldered or otherwise helpfully ignored.
If you wish to continue the conversation and eventually achieve a delisting, you must make sure you receive our responses. At least you had the decency to write to us from an address that appears to exist. We will not try to jump through any hoops to maintain communications with you.
