Vodacom Insurance Issue

Vodacom again... second review in 1 year -- I upgraded in April of this year and took out insurance with my upgrade on my cell phone. On the 07/09 my phone was ****** - I went into Vodacom to submit a claim. I had to get an affidavit for insurance purposes, which I did. Everything was submitted to Vodacom for the claim, only to be told I don't have insurance. Apparently Vodacoms 'system' cancelled my insurance in June without my consent / knowledge! It's a month later and still no progress - I've emailed backwards and forwards, still nothing. I don't see how Vodacoms 'system failure' or whatever you want to call it is now my problem - I confirmed insurance on my phone, therefore surely I have the right to claim....apparently not
