Really at a loss what to do with Rain

So my experience starts three weeks ago with Rain's website upgrades that prevented me from making my debit card payment which was continuously declined. I was cut off and had to battle for a few days with phone calls and emails for Rain to fix the problem. When that was finally fixed last Friday I was connected for a brief few hours. I had decided to upgrade from the R250 to the R479 package. The app and the website wouldn't let me make the upgrade so I lodged an email. I was also then disconnected from the internet not being allowed any access whatsoever even though every device I've put my Sim into shows there is 4G connectivity. I then lodge another query with a Rain rep on Friday. On Saturday I have no feedback and still no connectivity. On Sunday I call in and the centre says they will get back to me. On Monday I make another query. And still nothing which prompts me to email egain. A technician phones, tries to fix the problem but can't so he says he'll get back to me. Throughout this week this cycle of me continuously having to ask for updates is repeated. Now today it seems as Rain is ignoring me.
