Although the complaining company has left a phone number, it usually won't answer it if it calls, because it doesn't want to cancel the complaint at all. Of course, it is not excluded that some complainants understand your situation and agree to cancel after patient communication.
2. Make a complaint
If the seller doesn't have any infringement, but is complained innocently, he can click Complaint under the complaint product and submit his own evidence and written explanation for the complaint query. If the other party's complaint is not pressing, the chances of success in the complaint are still very high. Of course, if you do have infringement, plus selling fake goods, it is useless to complain, because you deserve it!
