Abu Garcia gt20l overhead reel problem

 Hey everyone I just got a Abu Garcia overhead combo just a few weeks  ago but I got myself in abit of a tangle as  what happens with them reels anyway after untangling i reeled it in and it made a cling noise and now when I reel it in theirs not drag pressure :s I'm really unsure what to do I have a general idea but is it easier to just hand it into a servicer?
