Clay Sim — Don't use the clay sim service at all

Guys, if you ever decide to use a clay international sim card for any destination, please ensure that you cross check your bill 10 times before clearing it off. Best would be that you keep the payment by cheque or cash than auto debiting it on ur card. Because be rest assured that they would definitely charge you more than the actuals and then the refund process will take forever. I have burnt my fingers like this over 11, 875/- rs which were excess that they charged on my card for the sim card that I used in Shanghai. The bill was actually for 8745/- only. And I was charged almost 20, 000/- for it. Best would be don’t use the service at all.
