I want to leave Smarty - not at all happy that I cannot get through to a human

I haven't received my SIM and I cannot get through to speak to any person.  Your customer service set up is ridiculous. There is no telephone number.  How on earth can anyone resolve any problem at all. 

If I receive my SIM I will not activate it . I will look for another provider. I am so disgusted and frustrated at this situation.
