Furious on the last 2 days of working at the ex-working place

It's my last week working at the company. I thought i could leave peacefully but something arose that i never expect to happen.
6/3/09 was my last day in the company & i never expect to leave the company with anger & being pissed off by the attitude of my boss!

On 5/3/09, in the morning, the audit manager received a letter from LHDN saying that one of my company's client get penalty for submitting the tax file late for a day. The client's company name, I name it as AR. My boss was furious to know about that after the audit manager told him. Me & my senior didnt know about this matter. Until it was lunch hour, when we were at the food court eating, the audit manager called up my senior, in a very heavy & angry tone asking who's the one to submit the file that day. So my senior said it's me. Then the manager asked what time i arrived there. Then senior said at 5.30pm. Then manager asked where i put the file. Senior said she asked me to put into the box at the entrance of the tax dept as the office was closed that time when i arrived.

Then the manager kept quiet for awhile.....then she said that the boss wants us to see him when we're back from lunch. My senior was quite nervous that time & keep thinking of what to say when we go up. But i kept asking her to calm down as it's not out fault. It's the audit department whom gave her the financial statement at the very last minute to compute the tax for tax submission. The last day for the submission was on THAT DAY ITSELF!!!!
The audit only gave her at 3pm. She tried to finish it up at 4pm then she passed it to me & at that hour, i quickly rush out from the office. When i get down, i quickly walked to the front bus stop to grab a taxi. After waiting for quite a long time, i only manage to grab a taxi to Pandan Indah. By the time i went into the taxi, it was already 4.45pm.

After knowing the incident, my boss decided to ask my senior to leave the company earlier. She resigned but have to give 2 months notice. My senior was so happy to hear that & agree to pack. Then the boss asked us to leave his room. On that day before i leave the company, the lady boss asked me to see her. Then she asked me again the question......AND.......BLAME ME FOR EVERYTHING! She said that this is the first time they send the staff off early. Usually the staff will work till the end of their notice period. She said that my doings made them to decide to ask her off early. She said that i'm irresponsible & didnt protect the company's interest.

I'm damn pissed off when she put all the blame to me! I really wanted to shoot her with my words the next day but she didnt come to office. So i missed this chance.........anyway, there's still another.......when my cheque's ready for collection
