Wrong Principal applicant name in visa

We got our visa stamped for me and my daughter but the name in annotation section for Principal applicant is somebody else’s name and not my spouse name. We have sent mail on this to embassy and they said the issue is escalated and we will contact you as soon as we receive a response. We previously planned for 14th and now moved our plan to 18th of July. But seems we have to cancel our tickets if this issue is not resolved soon. Does anybody have faced same issue? How much time does it take for this correction. We have not made any mistake in DS 160 form so hopefully it should be resolved soon.
