"Mistakes and poot customer service"

I am building a house and the electrician of choice is el-experten. This is unfortunate as their services until now are very bad. We had an initial meeting which went well, but after that they did not respond to mail or calls, made mistakes in drawings and were generally unprofessional. Now there is a mistake that apparently I need to fix or pay more, because their representative didn't account for building materials. Call me to fix this...
