Very bad experience with Clay Sim Cards --- Hi, I had heard a lot about clay international sim cards and thought I should use it for my next trip to London.  So I placed an online inquiry for someone to call me and explain the entire process of obtaining the sim card and the documents they would require. I have to say, the first call that I got was after 2 days of putting that request where the sales person (I don’t remember his name) was very eager and spoke extremely well about Clay and its services and said that he would be there the next day to deliver the sim card. It has been 4 days now, almost a day away for my trip, and I have been calling that person with no response. I have never experienced such poor services in my life, where the client seems to be more interested in using the service than the company selling it. I have already learnt my lesson with this experience and I can imagine how poor their services must be.
