Unecceptable service

I received my simcard last Wednesday , and later a SMS stating that my sim was successfully activated. Since then I have being struggling to use my simcard. I contacted Rain through their Facebook page , but nobody seems to be able to sort this probleem out. My phone doesn't pick up the SIM , just say " no SIM card". I put the SIM in another phone , same problem. I really fed up struggling with pathetic service providers. I'm going to lodge a complaint with ICASA. Perhaps I will get better service there.
