Best method for feedback/complaint/resolution seeking

On the whole I am very happy with my VS experience.
As a frequent VS flyer I suppose I am, however, more likely to run into customer service issues than, for example, an occasional leisure flyer.
Can I ask what method of communication (and to whom) has proven most successful in terms of either having a complaint registered, or a resolution forthcoming.
I've found Twitter to be particularly good at sorting out a problem quickly (no doubt because the issue is, in effect, public, so VS need to be seen to be acting quickly).
In terms of registering feedback (either positive or negative), I've written hard copy letters and used the online feedback forms (both to general Customer Service and to Flying Club) with mixed results.
I'm in the process of trying to both commend a VS employee who finally sorted an issue out for me, whilst also explaining to VS the sequence of customer service and IT blunders which caused the problem in the first place.
I'd like both for that employee to be recognized for his sterling work, and also for VS to look into how the problem occurred to help future passengers in the same boat.
(The problem in short: miles redemption taxes misquoted on phone by minuscule amount, so e-ticket unable to be issued because FC figure did not match Ticketing Dept figure, cue this circuitous conversation six times, "Where's my e-ticket, please?" "It'll be with you in 24 hours." ...for over a week).
I'm not looking for anything in return, nor to attack anyone; just for someone at VS to actually understand that there is a problem which needs to be fixed.
Speaking of which, this is quite an interesting read: http://online.wsj.com/articles/the-art- ... 1404947542
