Terrible customer service
Terrible customer service. The mobile number porting over from Singtel was not complete and so we were sent two bills - one from Singtel and another from SIMBA. Singtel is at least trying to help resolve the issue but SIMBA does not try to understand the issue nor help at all. Plus, all responses are provided at night often at (2-3 am) and so you have to wait a day to get an answer.
