Dear sir,Since 9am, I keep calling your customer service number. Up to recent, I made calls more then 30 times unfortunately, i only receive answer machine. Again and again! so irritating. You just make my telephone bill increase for nothing. Waste my valued time and soo peace out.My complaint is about your poor coverage at my office area, which is located at Sentul Pasar. For your information, i has 50 staff that using Digi post paid and prepaid. We highly recommend Digi line to our foreign worker due to your exciting international charges. However, regard the local connection it seem always interrupted, slow loading speed, cant hear the calls clearly and very bad coverage.Please take immediate action and reply my complain officially. Thank you.
