Lack of communication and unfair ruling

I am digested by the service I received today. I ordered myself pie and ****ins from woolies and my driver was to arrive at 1:05.. at about 12:50 I lost connection and luckily I saw that and by 1:05 my connection was back and then I received a notification that my food was delivered. The driver left with my food and didn’t even bother to give me a call, why do I have my cell number if you can’t call or text. The connection lost was internet but calls could come through, I tried to report on Uber and they told me they can’t refund. Why didn’t he leave my food with security and leave then!..he didn’t bother to call me or ask them to me!.. I was left hungry and broke cause they are refusing to refund me. I want my money back, I had no intention on spending 100 bucks on someone I don’t know! I want my money!
