Vlookup multi date in one cell

Dear Expert,
In my attached file my data table range is A1:D17
column b contains my vlookup criteria & column A,C & D is my criteria range.
column a contains date which is sequence like oldest to newest.
column c & D also contains date but its no sequence, can be same always or same.

In my attached file f3 is my lookup value, i need g3 & h3 result which match column c & d based on lookup value.
if lookup value matches c or d column all data are same then it will take it will take any one or first cell data but if lookup value matched multi date then it will take all date & separe "/".

i3 will lookup value first match data on column A & j3 will lookup value last match data on column A.

In attached file i do it manually which is for your ref. but need it with formula.

Please help me in this regard.

Dear Expert,
Your code is working properly according post 1 but when my table range is increase H column data is not coming.
In my attached file previous i am working data row up to 17 but my actual sheet data row upto 1955, when sample worksheet data row extend up to 1955 h3/h4/h5 result not coming accordingly.

Another need to correction like G & h column data is corect on your last provided sheet but here coming only 2 date oldest & newest but i need all unique data of C & D column considering lookup value.

Attached file for your ref.

Please pay your kind attention.
