I am now in digi postpaid plan. Currently using 016. Can i still use this 016 number if i switch to U-mobile?

Is there any complaints or bad reviews on the 3G lately? I have done some surveys and it seems that maxis 3G is quite unstable.. I'm now changing from Digi family plan 30 to U-mobile postpaid which cost RM 28/month? Is it worth it?

U-mobile and Digi service customer service sucks! I went to u-mobile last week to change from Digi postpaid to U-mobile Postpaid U28. Then they told me to wait 3-5 working days. So i waited for a week plus but i didn't receive any news or sms. I call up then they told me to wait for another 3-5 working days. So i waited again!!! After 5 working days, STILL NO NEWS. I call up again and they told me to WAIT ANOTHER 3-5 WORKING DAYS!!!! I got mad at that moment and scolded them. The staff is also so blur and they always push their jobs to another staff.

I received a message today and it stated there " Failed to port from Digi to u-mobile. " I dont know how they handle their job. Next week is some more a public holiday and i have to wait for another week to go to the centre.

Poor management. Poor customer service.

NEED HELP ON THIS!!
