unbelievable service, i tried to call them on last Wednesday regarding my power bills so high, and they suggest me to pay extra as a service so the electrician can check my metre box to make sure is there any faulty on the metre box or not, they said its 3 business day and they asked me to call them again on Friday. I tried to call them on Friday and they said i should call them again on Monday. So i tried to give them a call today still no result. Unbelievable i just speechless with their customer service that make a deep breath sound during our conversation. I tried to ask them nicely and their response is with deep breath sound when i talked ? Seriously? and you said the conversation are recording for training purposes. Well you should train your customer service provider how talk nicely. i can't believe they hire someone that can act so rude on the phone.
