Bad service received on a broken screen claim for iPhone 6

I have experienced the worse service with regards to a claim for my damaged screen on my phone(iPhone 6s Plus) I am being held by my neck on a request for last date of use from the network service provider which the network service provider (vodacom) has indicated they can’t give cause no phone calls were made or received on the phone whilst it was in use as the phone was mostly used on my home WiFi for FaceTime and app downloads for gaming for my daughter. At no stage of insuring my devices was it a clause that the phone needs to have an actively used SIM card, I have provided evidence of game purchases with screen shot dates for the device as well as the last IOS that was updated for the device which only came out in November and I have a number of times informed the claims administrator that the evidence of usage is on the actual phone itself in terms of the phone log for FaceTime, date of when games were download and when software was last updated: screenshots or pictures taken on the phone under the gallery and other evidence and find it very unfair that a claim will be held hostage by SIM card usage in this 4IR when most people use their devices on WiFi as a a pose to on a particular network as we are in the new age and not the dark ages.

I have so many devices insured with King Price and my vehicle and if this is the level of service I will be getting during claim stage I’d rather move all my insured products to a more up and to date service provider who understands we are not in the dark ages.

My claim reference is CKP***/2 and I have claimed before for a tablet and such information was not demanded from me hence I am shocked and confused.
