Reimburse the remaining balance!

After my claim was approved for the same device I was using, I couldn’t find a new one on all Vodacom stores except for CPO and I wanted a brand new. I checked istore and found that they only have iPhone 7 which was 500 more than my cover amount (R7500), so I called and asked the agents how does it work if I wanted to get it from istore, and that’s when I was told I will buy with my own money and will be reimbursed. I asked how will then the excess work this time around, I was told that no, excess issue will no longer apply the same, they will reimburse me the full R7500, and because of that provided information I went ahead with my purchase decision. Now I receive my reimbur*****t and they deducted the excess amount that I was told would no longer apply. I confirmed with more than one agent if indeed my refund would be exactly R7500 and they all confirmed so. Can FINRITE please pay me the remaining amount because I will not suffer for their agents inability to understand their products terms and conditions, you can listen to voice recordings and if I’m not responded to regarding this, I’m going straight to ombudsman! If I was told the excess would still apply the same way, my decision would’ve been something else because 15% is a lot of money and I would’ve planned according to my budget!!! Please refund the rest of the money or ombudsman’s will solve this for me, and because I’m backed up with all the voice recordings I WILL WIN THIS CASE!!
