Mission Creating Self Service PIN and Painful Verification Process

Everytime I call Cell C on 140 I am given the opportunity to set up a Self Service Pin. So today I decided to do exactly that. 1st Attempt. I called from my other CellC Number and went thru the complete process and passed the Verification process. However the CSR did not advise that I had to call from the same phone as I wanted the service on. (SIM is in a Modem/Tablet). The IVR cut the call .. Sorry! 2nd Attempt Called from Samsung Tablet (Number ending 7859) After 3 attempts finally connected wth a CSR. Went thru the standard questions and we proceeded. However this time I failed the Verification process twice and I could however not continue. I answered all the qestions correctly in my opinion eg. I dont have a house in Vosloorus! I have never been a Director of Sanlam! My ID does start with 52!

Is there not a less frustrating way to create a Self Service Pin.now really So if ITC has the wrong information on me, I am not able to activate the service.
