Clay Sim Card Customer Rating is 0 for me --- I had taken a clay international sim for China and i have to say that their customer services are really poor. I called them as my sim had stopped receiving signals mid day and whatever i did, nothing was helping. Instead of helping me, they kept on transferring my call frist from the technical team to the customer service team and ultimately said that this was a technical glitch which would be sorted in a days time and then hung up. The issue didnt get resolved for 3 days and despite several emails and calls, nothing changed or infact there was no help from their end at all.
