I have been struggling with signal for the past 6 days

I have been struggling with signal for the past 6 days. And been contacting PluxNet on their WhatsApp channel where I was then asked to send proof of payment. I did send immediately and from there there was no response. Yet I kept on following up and asking for assistance with signal. Nothing was done. Today again I contacted them and I was again asked for proof of payment. What is this PluxNet. Why do consumers suffer for what is paid. And your WhatsApp consultants answers one text after an hour and still no service. I'm tired of this. Please refund me I can't do this horror anymore
