This number has shown up 4 times on my caller id today. They will not answer when you call back - it says thank you for calling payment service center then you hear beeping.
Looks like it is ClearTel
This number will call not leave a message and when you call it back - it says "thank you for calling the payment service center" hold a minute and someone will be with you. Then it goes busy.
This number keeps showing up on the caller id - when you call it - you get a busy signal
