Clay Sim — Useless Clay sim !

I am currently in the US studying and it thot it is apt that i write my experience o[censored]sing a Clay Sim Card. My dad got me a student plan from Clay wth the view that things will be very convenient and will be relatively cheaper infact the sales guy also told me that its damn affordable.. i will get to talk more for lesser money !! All bloody !! Total NONSENSE!! My father got a bill for 30k for a month for calls being charged to their number when its late night in India, and for random minutes. I have call records in my phone that prove otherwise! My dad had to prove their fraud of overcharging minutes with my records and his own phone records, and got a refund thereafter!! Never use Clay Sim cards for anything ever !!
