Need advice in rental issue.

Hi,
     I just gave my  landlord 480,000.00 cash for a year's rental for my home in Hikkaduwa.  I rented for 6 months the first time..  The first time I paid a lawyer $354.00 USD to "file" some paperwork for the rental agreement. My landlord told me I would need this paperwork for a visa which never happenend.  I asked if we had to do that again and my landlord laughed and said no it wasn't necessary and the lawyer had overcharged us anyway.  I found a solid rental receipt on the web, printed it and his wife (the owner) and I signed it.  We all agreed that was fine.  This was two weeks ago,  Then this morning, I had to call him with an electrical emergency (the sockets were spewing fire...).  This pissed him off that I would bother him so he and his wife showed back up this afternoon.  They stated that because of my actions, they had consulted a lawyer and demanded 96,000 rupees to be pay NOW for lawyers fees.  I think this is just a power play.  I told them I won't pay them a dime. Then they said they could talk to another lawyer who would charge less.  I told them I wouldn't pay another dime and would move out if they needed me to.  I was very nice, but I am not going to pushed around because the were inconvenienced by their property.  I will happily move out even though I know I will never get my years rent back. Is this legal and customary to pay almost 30 percent "lawyers fees" for a rental home?  I only pa 40,000 per month. I pay for all of the repairs and materials myself.
Any  advice or insight would be greatly appreciated.!!
