Declined claim

On 29 July 2022 I lost my phone on my way to work, to my dismay my claim was declined due to "usage". I explained to the consultant that vodacom issued me with 2 sim in addition to my prepaid one so I had 3 sim cards in total, the phone is a dual sim so I was alternating between the 2 contract sim. Now because of that my claim was declined. I'm so disgruntled by this whole thing. I just want to cancel my contract and cut ties with vodacom altogether.
