I am so fed up with this

I have complained several times this week that my network is unstable and very slow, did I get any help or just a message that says please reboot ur router and a message that says thank you for contacting HYPA before I could even explain further, I am on a prepaid account so cut of date should be the exact day I paid the previous month. But guess what my WiFi is off today and I bought my voucher on the 24th on top of that it was not even working properly and again the is no response with my query
