phone won't ring calls go straight to voice mail

So many customers are facing this problem and t-mobile is asking basic questions to buy time or not do anything. It's really pathetic.

I get calls sometimes and sometimes only voicemails.

T-mobile sucks.

I think when all customers decide to switch, then t-mobile will wake up but then it will be too late for them to take any action.

t-mobile customer service sucks big time, really pathetic.
