Vodacom does nothing to help their customers

In March I got my upgrade and the lady that assisted me advised me to take out insurance which I duly did at that time. Not two weeks later my phone broke. I contacted her and she said I will not be able to claim from insurance as it was not an out of box damage(screen got cracked). Took my phone to another cellular repairs shop who sent my phone away, after a battle to get it back, it was returned to me still damaged. Sent it to vodacom repairs in Umghlanga through pinetown branch. Irrepairable. I was advised by Hendrick the manager to try claim from my insurance. They can't help me as vodacom only activated the insurance in APRIL! This after I had done my upgrade. Contacted branch for a resolution, they cannot help me as there is no proof that the lady who assisted me activated my insurance in march. The refuse to help me this with a contract I am still paying for and insurance I cannot use! Disgusting! I need assistance to sort this out!
