Battling Rejection

This is supposedly done last week but I had to get my act together before coming up with a reply letter to a somewhat "summon" from a previous employer which I received 2 years ago.
Let me take you back to the year 2010. It was the glory year of my life or so I thought it was. I landed a job in my alma matter during College. In just a matter of 6 months I got promoted. They offered me a graduate studies scholarship in a prominent University which I wholeheartedly took. Everything went smooth sailing until I sent some memos to all Offices regarding an admission exam for Freshmen who are already enrolled by the way. The letter contains some defense statement to the administration that  I purposefully indicated to avoid raising of eyebrows. But to my dismay, the President herself misinterpreted it and perceived it as something 'personal'. The chain of disappointing events began. Our VPAA wasn't renewed and was replace by a mediocre who was a pathological liar. Until such time that I was reprimanded to explain myself in 24 hours as to why I filed for a vacation leave with "personal reason". I stayed humble and submitted to everything they want me to do. I even kept mum when I was ask to sign the memo about having an assistant and I was never given a feedback. I could go on with a long list of those psychologically disturbing treatment but the last straw was when they denied my October 31st salary. I begged for it for I only had 20 pesos left in my pocket and I needed 25 pesos to go home. They never listened, they continue with the mocking and I could see their fangs. What's worst is that they were too proud to call themselves "christian".

I headed out of the gate around 5:30pm and went back to my office to finally get everything. For me, it was the place that I never want to set my foot on again. It caused me emotional distress big time. 

For one year and 11 months I chose to work at home. It was the safest place. To be in isolation. I am oblige to no one and I had more time with my family and few close friends. 

But somehow, God Almighty exhibited His love for me again. Another career opportunity came through a previous colleague. It was worth a try for I've been with this employer for seven months now and it feels so homey that I am more than positive this is my last stop.

So now, I'm still trying to figure out how my response letter to that "summon" should sound? Or what will I even have to say? Gosh.
