VODACOM CAPE QUARTER SQUARE FAILED TO HELP ME!!!I HAVE A CONTRACT.

I have a contract with Vodacom for over 6 years now. I have an Apple iPhone and I am unable to charge it, so went to Vodacom Cape Quarter for assistance as I have insurance and they failed to help me. They advised that I should switch off "Find my phone" so that they don't get charged as a shop. I am unable to switch it off as my phone is off, I don't have another apple gadget,I don't have my password. I have been trying to reset it and called iStore, they also didn't help. I am frustrated as I use this phone to pay accounts, transfer money home. I'm still grieving the loss of my Dad, I don';t have another phone I have to use work laptop to communicate with the kids. It's alot.
