Rare but it happens! Her faulty water heater switch have destroy her ELCB (something in her main switch board). It was late and my colleague is tired , gave the wrong pricing…cause friction…in the end I apologized and sent them the right pricing although we agree on a higher one…guess what, we are just not perfect but we don’t cheat people! We replace the ELCB and everthing is back on… we also discover that the other ELCB for the lightings (high end residential at times have 2 ELCBs or more) is faulty, it doesn’t turn off the lights but it doesn’t trip if there is a short circuit. Due to the miscommunication, my client didn’t opt to change it to. Anyway the main problem is solve but the other ELCB is not change till now…can’t really blame my colleague, guess he is tired… If you guys that is reading this wanna give us another chance, please call for us in Mont Kiara if you required an electrician services. Nevertheless I apologize to Mr Goh on this occasion for the lousy experience we cause (He may be the owner who call us).
