There may not be a proper term for precisely what you describe but if there is then someone may be able to answer your question on here. There is a term called vexatious conduct, used particularly when frustrating or needling someone within the litigation process and in effect causing trouble and using procedure to do it - this may be of some relevance to you. You clearly don't want to reveal the nature of the dispute, but if it is a consumer matter then I sympathise. My experience of such disputes is that while there are a number of ways to get advice and sympathy (including astonishment as to what some parties get up to, indignation at the blatant contempt) there is no organisation around to solve this sort of thing outside the courts. Although there are trade bodies which will take on a role of sorts, they are paid by their tradesmen members so are by definition not impartial. In my case (perhaps like yours) I had lots and lots of paperwork but the relevant staff were overruled by the hierarchy and the matter was thrown out because there was no way but to find in my favour. My case ended up in court which was an eyeopening experience: Bending of procedure to favour the businessman and an inequitable final result (I won 75% of the argument but was made to pay the business 75% of their costs). I also found that solicitors feel they are at a disadvantage against companies whom they actually find intimidating. Finally, the deeper pockets can hire the more forceful representation, even unscrupulous ones - but it is an adversarial system looking for a winner, not fairness. Whatever the court decides, fair or unfair, is by definition justice. As I was, you are almost certainly very much on your own - it is a wretched situation.
