SHOCKING/NO CUSTOMER SERVICE IN TRYING TO RICA SIM

Absolutely shocking customer service!!! Got SIM card two days ago, purchased R479 unlimited 4G for any device and have been trying unsuccessfully to RICA online. Each time I try, I get a message "check your messages – tap the link in the SMS we sent you to get going" - I HAVE YET TO RECEIVE AN SMS! After two emails and FIVE phone calls (confirming all my personal details over and over again). I keep getting told that my issue has been escalated to RICA department who will contact me shortly. I STILL have no email response, no SMS and NO callback from RICA department! Their disclaimer states "If you cancel in your first 7 days, you'll get all your money back." I can't even get to an option to cancel!!! Most frustrating and worst service I've ever encountered! Have spent a small fortune on phone calls to customer care and still no internet connection! STAY AWAY FROM RAIN INTERNET SERVICE PROVIDER!!
