I was with celcom for 11 years. Went to sunscribe the most expensive plans available for the internet quota and other perks. Due to covid i have been using wifi instead of data. But @celcom line is really bad. I couldnt access internet when i am out in KL. Basically didnt get what i paid for. Internet quota available but no signal. Hence i opted out after 11 years. Celcom never bother to check on me even after 11 years as if they dont care if they loose their customers. Suddenly after close to 3 months, some random number called telling me i have outstanding bill whoch i have never received from celcom. These people yelling at me telling me to go to celcom center (why should i anyways?) If you want the money, bill me professionally. Now to get the bill, they say i need to pay RM10 for the bill to be emailed (a bill that was never sent to me, but demanded money for). Even J&T cost cheaper than that. So glad i opted out from celcom. Bad coverage. Expensive charges. Hidden charges. Bad customer service. Unprofessional company.
