Urgent assistance required

My father and I went to enquire on a ITC (to blacklist his ****** cellphone), we are still in the woods, he went to the Cell C in Zevenwacht Mall to no avail. I the assisted him in calling the Cell C call centre who then assisted us but due to my father being of age, he could not remember his last recharge date and failed the security questions. The lady who assisted us were very courteous and understanding that my dad is not technologically sound and due to him being almost 70 years of age. I do understand the reason for the security questions but due to the age factor as well as the level of education as well as the ***** going around, I feel that some systems should be set in place to assist our elders. My mother purchased the handset for him, and now he is stranded without a source of communication. We would like some further assistance in this matter, because if this is the case then we're in for a more daunting period of living. It is scary to observe how the system is setup, look, I understand the protocol and reasons for it. But consider our elders. Kindly communicate with me via WhatsApp.
