Bad Service from Telkom

Good day

My phone was recently stole so I needed proof of purchase or invoice for the device I am currently using to claim from insurance, however I am getting the run around and the lack of staff assistance is frightening as they do not seem to be bothered, I have contacted sales who directs me to accounts , from accounts i am directed to the store, the store states I need to phone sale again and it keeps going on in circles, the phone was taken up telephonicaly, the consultant then states I need to phone the 3rd party company that sold the phone to get the invoice . When i try Sales Direct they cannot pick up the call made, the other number for Mondo is invalid, what kind of network is this that you have to go through different channels in order to get one invoice
