Bad customer service and lying

I ordered Pizza on the 16th February from Debonairs Isipingo branch. When I called in, I was told that there is no electricity in the store, however 3 minutes later I placed the order online the order went through to the same store and somebody called to confirm my order. My issue is that nobody took accountability from the store manager to the people at the Debonairs call centre, they all shoved me from pillar to post and also passed the buck. Nobody whatsoever took the matter seriously, I also sent a direct message on their Twitter page and even there as well my complaint sort of fell on deaf ears. The thing is with stores or brands like Debonairs they only take your complaint seriously if you are influencieal and have a huge following on social media. If you are an ordinary person like myself you will just get an "i am sorry it will never happen again"
