Contact an electrician to check the meter set-up. Look online for a reliable service guy to come out. Do it without your landlady knowing. Remember, Thai Rak Thai... šš. You pay an excessive amount based on your usage. Look past the noise on here..
You will love Thailand. Make it work. Jump thru the loops, and forget 'bout all these nay sayers that would like you to stop at every yellow light. Take the risk and come. It's an awesome experience. Thailand will be your education.
