I got similar problem with Celcom Broadband. I purchased the E220 modem at RM990. I started with RM68/ month package. But what unable to get connected to yahoo mail consistently. I only managed to get 10% successful connection rate to yahoo mail. So I called up many times to celcom customer service, and you are right, they gave crap service or lips service. No actual or capability to help me to resolve the problem. Then, I decided to upgrade to RM98/month package, thinking this may help resolve the problem.
End up, the same, hair-pulling frustration expereince for months...
The government is to be blamed!!!
Celcom is the only choice when I signed up!!!
Celcom is cheating us, the malaysian people, and the government is the caused and doing nothing about it!!!
Celcom's contract is so bias, which is wrong...
We are not getting what we actually paying for... the result, not the infrastructure.
In my opinion, Celcom is truly the "Undisputed, fastest, best, widest" cheating GLC in Malaysia!!!
