Vodacom Bullying there way out of Insurance claim

In December 2013 I had an insurance claim that was short paid due to the consultant who did my upgrade not following through with insurance upgrade. I was made to pay over R5000-00 due to that persons mistake, as Vodacom claims I have no proof that I instructed the insurance to be upgraded. I lodged a complaint and was never reimbursed,as a matter of fact the matter was never even investigated or dealt with. <br> Upon the replacement of that claim, I had to sign documents for new phone.At that point I signed the documents and IN WRITING noted the upgrade on insurance was requested on my behalf.<br> Last week I had app**** for an insurance claim again due to accidental damage, Claim again is being underpaid due to same excuse. I supp**** my written notice as proof, and now Vodacom customer care is referring me to Cellsure, who Is refusing to settle according to the phone value unless I pay difference in 15 months premiums and over 25% excess. <br> I was not responsible for the Insurance upgrade not correctly being issued in both cases, I asked the consultants & they assured me that my insurance is Upgraded. I took their word for it. I have proof I instructed them to upgrade my insurance.
