unit transfer

I was confused in the project manager role as there is hardly any client interaction and disturbed at my technology(networking/telecom) proximity so thought that I should move into a vertical specific unit for more direct client exposure and revenue bottomline. The resume showed a vendor name that was transforming itself from networking to applications level and the rebranding is still in process so I have to explain the same in the initial few minutes and then they say there is disconnect.
I took my grievance to my boss's boss as the strings of my recent bosses showed no inclination nor support in trying to understand my woes as it is not acceptable practice to make such request. Neither do they have the power.
He mentioned about the recent promotion and how they had done it even though I was not performing the role. For me it did not matter as role entailed no monetary change.
He asked me about my core competency and I said project management blah blah and he said I was too early for that. I started talking about technical skill set I have written few client applications on windows.
He was clear that it cannot be done in the next 6 months. In the mail he mentioned 1 year.
Then I took personal grievance of a senior in group who sometimes loses temper and uses shouting as a mode of communication. He said it would not help him change his decision of timeline even though he would address this matter.
