If wish there were some place where i could formally lodge a complaint against the pathetic customer services rendered by Clay Sim Cards. I bought a sim for Japan and paid 99$ for unlimited data plan. Turns out that this data never got activated!! I tried doing everything possible that the cust execs asked me to, but all in vain. Moreover, i was bombed with a bill of 10k for 5 emails and a whatsapp texting!! Technically these cheats took almost 6000k for data activation and charged 10k over and above!! Never use their services ever!! OK
