I was cheated and robbed by Celcom.. i just came back from overseas last month. But my bill exclated from RM44 (38 first basic) to RM97 and followed by RM103. no even one calls were made in the last 2 mths since swear i swichted to other sIM card when i was overseas. Today i went to Celcom customer service Jalan Ampang. When i requested to see the manager. Immediately the staff said no managers around. Meet only by appointment. What customer service is this! Horrible service!. I will write in detail later. This is a true fact and I am about to bring my complaint to aduanskmm@cmc.gov.my tomorrow.
