Cancelation of the wrong contract - Consumer Complaint for Vodacom - Head Office

In December last year I canceled one of 5 my contracts but Vodacom canceled my daughter's contract also which was not sappose to canceled and I spent the whole January phoning them to try and her phone back on contract they eventually get it back on in the end of January and I asked them if they put the insurance back also they said yes. To my surprise two weeks back my daughter's phone was stolen and when I try to claim I was told the phone was off the insurance since January Vodacom canceled this contract by mistake and I'm the one paying for their stupid mistake I've already paid more than R8000 for their mistake. I want Vodacom to own up to their mistake the put me in this mess they must fixed it
