Jenny: Did you inform CHC your condition and seeked time from them to submit meds and PP
IF yes your case is active. It will take about 2-3 months after PP submission to get the PP back.
If you sis not inform CHC about your condition at that point in time, your file may be closed. It is better to send the query to CHC and clarify
