Hi Margaret, we have had the same probs and have lived in our villa for 3 years!! Ours affects our internet modem, not enough power to connect to ADSL, also lights dim, oven slow etc. Our elec surges up and down. You need to go to Tedas or get a Turkish person to telephone them. They have been out seveal times to us and upped our power, first time we were only getting 140volts!!! and it should be 220volts. We still have intermittent probs, but it has improved. We have borrowed a voltage tester and monitor our electric, if you know anyone who has one might be an idea to bring it with you. If you hve no joy with Tedas I do have a mobile no. for one of their engineers who's English is quiet good(think he is the only one!)
