Resignation not processed - will this incident create any problem for me in my latest joining?

I had been working as accountant on permanent post central government, after selecting in Sr Section Engineer(SSE) in Railway , I left that job and get relieving letter to join SSE post. (they mentioned the SSE posting place in relieving order.)
And , then I joined SSE training in August 8/2017....but due to some personal reason I had to come back at home just after 2 days. Since than I never go again there. And put the application of resignation on 19/08/2017.
But till today , I did not get any response from that side. It pasts more than six months.What should I do now?
I have to join other government job in this month. will this incident create any problem for me in my latest joining?

You are a govt servant.
But actions are totally ignoring departmental rules.
You joined SSE training and then left for 6 months.
Peculiar actions.
Has your resignation been accepted-need to go there and find out personally.
You may find it difficult to join another govt department when you are unaware whether resignation is accepted.
