Assuming Jacky is an inhouse customer and not an external customer:

1. Contact Jacky directly and tell them to stop that behavior. A common threat is "the more you call, the longer it will take until I can get to your request, because while I am handling your messages I am unable to get any work done".
2. If that doesn't work, escalate the problem to Jacky's boss. Explain how many work-hours get taken up by unnecessary followup calls and quantify the business cost of that behavior.

If Jacky is an external customer: People like this are the reason why many companies have a call center. The call center agents act as a line of defense between abusive customers and highly paid professionals. It's their responsibility to appease these people, distill down their requests to the essentials and forward it to the specialists.
