I was travelling to Germany and thought of cutting down on my international bills, therefore rented a Clay Sim Card for the same. I was a quite unsure about sharing my credit card details with the man(who already looked like a cheat to me) who had come to sell the connection,but in good faith for the company i did, giving them instrctons that the final payment will be settled by cheque. I am ready to ignore the poor services in Germany that i came across, but not the fact that they debited the entire bill without my knowledge on the card. I had not even seen the detailed bill, before they deducted the same. The experience has ensured that these petty companies should not be trusted with anything, even services!!
