Rain doesn't take customers serious

I have been complaining about their poor internet connection for some while, and they decided to give me the101 pro router which was delivered last week Tuesday. So since then, we cannot access it as it says connected without internet. Called their customer service line and I was told to give it 24hrs to register on their systems. Still it didn't work, so I tried their Twitter account multiple times and no response from them. Tried their askrain platform on several times, and it has been escalating the matter since last week with ***. Tried their Facebook account and still no response. Tried again their customer service line: +*** three times today and no answer. Mind you all our devices are offline including our security alarm and cameras. I can't even access my online classes or my work emails. Then, you get a silent treatment with no way forward.
