Finrite / Vodacom Claim

Lodged an insurance claim for a ****** handset in MArch 2019. String of emails back and forth. Turns out when I upgraded with Vodacom - online, the insurance quote given was incorrect. I refused to pay in to upgrade the premium to the level to cover the handset as I paid the premium quoted. They eventually came back with an amount of R660, which I paid. Today they tell me: I need to pay R1300 more to bring said misquoted insurance up to scratch. Insurance should have been done instore...yet Vodacom offers an online option for upgrade WITH insurance. I need to provide proof of upgrade...done this so many times already. I have even asked if they are looking for a reason not to honour the claim. Service is pathetic, cant find a person in a senior position. Vodacom shrugs their shoulders, its their nominated insurer for heavens sake. I am beyond livid at pathetic service and bad ethics and business practice
