Run the below query and see if you get desired values

SELECT A.ticket_id,A.number,B.subject,GROUP_CONCAT(DISTINCT C3.value) as service,C.value as vendor,C1.value as category,C2.value as action
FROM tableA A
LEFT JOIN tableB B ON A.ticket_id = B.ticket_id
LEFT JOIN tableD C ON C.id = B.vendor
LEFT JOIN tableD C1 ON C1.id = B.category
LEFT JOIN tableD C2 ON C2.id = B.action
LEFT JOIN tableD C3 ON FIND_IN_SET(C3.id,B.service) > 0
WHERE A.ticket_id IN (28,36,149)
GROUP BY A.ticket_id
