Clay Telecom — Beware of the rudeness

I bought a clay sim card for Thailand and while i gave all the supporting documents and credit card details as asked by the sales rep, my sim still dint work when i landed in Bangkok!! Like any other person, i called up the customer support team seeking help. But they were sooo rude on the phone!! Told me my documentation was incomplete and bcz of which they cudnt extend any help on the issue!! Despite telling them that everything was shared and closed, they didnt agree to anything and just disconnected all my services!! So basically i paid for a service that i didn’t use at all!! Simply disgusting...
