Supplier broke Policy & procedures!!!!

The worst experience Ive had with an insurance company. Extreamly angry with what transpired. I spoke to a lovely claims consultant to log a claim, I was told a provider wilk be chossen & they will contact me to assess the damage. My son tried calling, unfortunately I was on a call & couldnt disconect immedietly. After I finished my call. Around 7 mins, I called back, he informed me a man came to take pictures of our faulty TV. African man, he left no card explaining who he was. We live in a time where kids are exploited & kidnapped. ********s are posing as policemen, as parents we need to protect our children. How does a company like DISCOVERY not have the ethics to vet who they srnd to clients homes. Im disgusted & angry. Anything could have happen to my kids. I phoned Discovery to voice my disgust & Not 1 manager or client service consultant has phoned me back. I phoned another 4 times, no one has contacted me back to explain what happened. Or tell me who was at my house. Iwas told the service provider will call me before coming out & arrange a time. This is unacceptable
