Smart Telecom

Does anyone know how to get Smart Telecom to actually respond to customer queries ? I have called them , emailed them etc. but no result. I got one email response telling me to call their Customer Service number.When I did , I was waiting for 20 minutes in a queue before I decided to leave a voicemail message .No one came back to me.That was weeks ago.What a joke!

"Its not magic, its Smart"

Well they're half right anyway.
