+1

I ported to Umobile because of their good service
Their customer service has always been non-existent or utter rubbish

Now that their service has also dropped like ....
with daily voice line dropouts (yes, drop outs in a daily basis even if I stayed in 1 spot)
prepaid USSD code always shows "Connection problem or invalid MMI code" even though it's correct
Reception going worst in good covered areas - we're getting Umobile network not available so often
slow internet in good reception (4/5 bar with H - I can't even stream a 320p video without buffer)
speed test now shows max 1mbps than before was like 4mpbs average

So I've crowned Umobile to be the worst customer service of all telco's in Malaysia.
This is written in my blog recently by my personal few times experience with their RUDEST customer service staffs and.. yes there's more, but wait, part 2 is coming soon..

Congratulations Umobile.
