Vodacom taking advantage of customers through insurance

Last year I bought an iPhone 6 with vodacom rustenburg waterfall mall and took insurance for it. So during the Lockdown it started giving problems and I took the device to their repair shop. Was assist by a lady whom told me she can't switch off find my phone so I need to contact Istore to restore it. So while I was busy with that I decided to put my Sim card on another device as the specific one was giving problems. So recently I decided to take it for repaire and be claimed under insurance. To my surprise the quote of about plus 5000 was send directly to me, within few minutes an agent called me to inform my claim has been rejected as the unit hasn't been active over a month. And it's active on the current phone on which my Sim was active on it. All this wasn't explained to me and why was I not advised on my first visit to vodacom repaire shop. This seem to be a loophole to not cover my phone therefore I shall request all my premium if they don't intent to repaire my phone
